Exploring the single digit numbers in Numerology

By Numerology.com Staff

In Numerology, the nine single-digit numbers are the building blocks of the study of Numerology. These numbers in Numerology represent a specific set of character traits, symbolism (spiritual or otherwise), and meaning. In fact, it's almost like each of them has their own unique personality!

By understanding the meaning of these numbers in Numerology, we can better understand the profound messages they are sending us, especially when they show up in our chart or throughout our lives.

With almost every calculation we do in Numerology, we reduce down to a single digit. And while there are some exceptions, such as Master Numbers or an Angel number, we will almost always continue to reduce until we get down to one of these single digits.

There are a number of places that these single-digit Numerology numbers can show up:

  • Life Path number
  • Name Numerology
  • Soul Urge number
  • Expression number
  • Birth Date number
  • Numerology compatibility
  • Destiny number

...and pretty much everywhere in your personal Numerology chart or Numerology reading! Get to know the divine meaning behind these single-digit numbers as we introduce you to each one personally:

  • The Number 1 in Numerology
  • The Number 2 in Numerology

Numbers, representations of

The totality of ways of representing natural numbers. In any number system, certain symbols (words or signs) denote specific numbers, called nodal numbers, while the other numbers are (algorithmically) obtained by certain operations from the nodal numbers. Number systems vary in their choice of nodal numbers and in their methods of forming algorithmic numbers; as written notations of numerical symbols began to appear, so number systems began to vary in the character of their numerical signs and in the principles governing the form in which they were written.

For example, the ancient Babylonians used 1, 10 and 60 as nodal numbers; the Maoris (the initial inhabitants of New Zealand) used 1, 11, $ 11 ^ {2} $, $ 11 ^ {3} $. In the Roman number system the nodal numbers are 1, 5, 10, 50, 100, 500, 1000, represented respectively by the signs I, V, X, L, C, D, M (cf. Roman numerals ).

Number systems in which the algorithmic numbers are formed by grouping nodal numbers together are called additive systems. Thus, in ancient Egyptian (hieroglyphic) notation, the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 19, 40 were represented, respectively, by the symbols

$$ \mid , \mid \mid , \mid \mid \mid , \mid \mid \mid \mid ,\ \begin{array}{l} \mid \mid \mid \\ \mid \mid \end{array} ,\ \begin{array}{l} \mid \mid \mid \\ \mid \mid \mid \end{array} ,\ \begin{array}{l} \mid \mid \mid \mid \\ \mid \mid \mid \end{array} ,\ \begin{array}{l} \mid \mid \mid \mid \\ \mid \mid \mid \mid \end{array} ,\ \begin{array}{l} \mid \mid \mid \\ \mid \mid \mid \\ \mid \mid \mid \end{array} ,\ \cap , \cap \begin{array}{l} \mid \mid \mid \\ \mid \mid \mid \\ \mid \mid \mid \end{array} ,\ \cap \cap \cap \cap . $$

The same numbers in Roman numerals are written I, II, III, IV, V, VI, VII, VIII, IX, X, XIX, XL. In this number system, the algorithmic numbers are obtained by the addition and subtraction of nodal numbers. The English method of expressing numerals is a clear example of the additive-multiplicative method of forming algorithmic numbers, for example: three hundred fifty seven.

In certain number systems, called alphabetical systems, numbers are represented by the same symbols as letters, plus other signs, e.g. dashes. Thus, the ancient Greeks denoted the numbers 1 to 9, as well as all the tens and hundreds, by sequences of letters of the alphabet, combined with dashes. For example, the numbers 803, 833 and 83 were written thus:

$$ \overline \omega \; \overline \gamma \; ,\ \ \overline \omega \; \overline \lambda \; \overline \gamma \; ,\ \ \overline \pi \; \overline \gamma \; . $$

Alphabetical representations of numbers were used by the Slavs and many other peoples (cf. Slavic numerals ).

Number systems are called non-positional if every sign used in the notation of any number has only one value. If the value of each sign depends on its position within the notation, then the system is called positional. The Roman number system is non-positional. Any number in the Babylonian number system could be written as a combination of two signs: a vertical wedge and a wide-angle wedge (see the example below). These signs were formed into groups from one to nine in the case of the vertical wedges, and from one to five in the case of the wide-angle wedges. The vertical wedge could represent 10 and the product of 10 and any power of the number 60. The sequential order of the digit positions was the same as it is presently. Thus,

$$ \??? = \ 1 \cdot 60 ^ {2} + 2 \cdot 600 + 1 \cdot 60 + 1 \cdot 10 + 6 = \ 4876 . $$

Since the Babylonian system had no sign corresponding to no sequence (our zero), there was no guarantee that the notation of a number could be read in only one way. The exact meaning of the notation could normally be established from the context. This type of number system is therefore called a non-absolute positional system. The ancient Babylonians did subsequently introduce a special sign corresponding to our zero. The modern decimal system is positional.

All known positional number systems are additive-multiplicative systems. The positional principle of notation of numbers in these systems is explained by the following theorem of elementary number theory .

Let $ q _ {0} = 1 $ and let $ q _ {1} , q _ {2} \dots $ be a sequence of natural numbers greater than one. Then for any natural number $ a $ there is one and only one natural number $ n $ for which the equation

$$ \tag{1 } a _ {0} + a _ {1} q _ {1} + a _ {2} q _ {1} q _ {2} + \dots + a _ {n - 1 } q _ {1} \dots q _ {n - 1 } = a $$

has a solution in integers $ a _ {0} \dots a _ {n - 1 } $, such that

$$ \tag{2 } 0 \leq a _ {0} < \ q _ {1} \dots 0 \leq a _ {n - 1 } < q _ {n - 1 } , $$

$$ 0 < a _ {n - 1 } < q _ {n} . $$

Given this, only one ordered set (tuple)

$$ \tag{3 } \langle a _ {n - 1 } \dots a _ {0} \rangle $$

of integers with condition (2) satisfies condition (1).

In the Babylonian number system, $ q _ {1} = 10 $, $ q _ {2} = 6 $, $ q _ {3} = 10 $, $ q _ {6} = 6 \dots $ etc. In the system of the Maya Indians $ q _ {1} = 5 $, $ q _ {2} = 4 $, $ q _ {3} = 18 $, $ q _ {4} = q _ {5} = \dots = 20 $.

A number system in which all terms of the sequence $ q _ {1} \dots q _ {n} $ are equal to one and the same number $ q $ and in which every number from 0 to $ q - 1 $ is denoted by a specific symbol is called a $ q $- ic number system or a positional number system with basis $ q $. In a $ q $- ic system, every natural number is denoted by a sequence of the symbols shown. In order to add and multiply the numbers in a $ q $- ic system, it is sufficient to have addition and multiplication tables for all numbers from 0 to $ q - 1 $.

decimal representation

Quick reference.

Any real number a between 0 and 1 has a decimal representation, written. d 1 d 2 d 3 …, where each d i is one of the digits 0, 1, 2,…, 9; this means that

a = d 1 ×10 −1 + d 2 ×10 −2 + d 3 ×10 −3 +⋯.

This notation can be extended to enable any positive real number to be written as

c n c n− 1 … c 1 c 0 . d 1 d 2 d 3 …

using, for the integer part, the normal representation c n c n− 1 … c 1 c 0 to base 10 (see base). If, from some stage on, the representation consists of the repetition of a string of one or more digits, it is called a recurring or repeating decimal. For example, the recurring decimal .12748748748…can be written .̇12748̇, where the dots above indicate the beginning and end of the repeating string. The repeating string may consist of just one digit, and then, for example, .16666…is written .16̇. If the repeating string consists of a single zero, this is generally omitted and the representation may be called a terminating decimal.

The decimal representation of any real number is unique except that, if a number can be expressed as a terminating decimal, it can also be expressed as a decimal with a recurring 9. Thus .25 and .249̇ are representations of the same number. The numbers that can be expressed as recurring (including terminating) decimals are precisely the rational numbers.

Natural Numbers

Natural numbers are a part of the number system which includes all the positive integers from 1 till infinity and are also used for counting purpose. It does not include zero (0). In fact, 1,2,3,4,5,6,7,8,9…., are also called counting numbers .

Natural numbers are  part of real numbers,  that include only the positive integers i.e. 1, 2, 3, 4,5,6, ………. excluding zero, fractions, decimals and negative numbers.

Note: Natural numbers do not include negative numbers or zero.

In this article, you will learn more about natural numbers with respect to their definition, comparison with whole numbers, representation in the number line, properties, etc.

Natural Number Definition

As explained in the introduction part, natural numbers are the numbers which are positive integers and includes numbers from 1 till infinity(∞). These numbers are countable and are generally used for calculation purpose.  The set of natural numbers is represented by the letter “ N ”.

N = {1,2,3,4,5,6,7,8,9,10…….}

Natural Numbers and Whole Numbers

Natural numbers include all the whole numbers excluding the number 0. In other words, all natural numbers are whole numbers, but all whole numbers are not natural numbers.

  • Natural Numbers = {1,2,3,4,5,6,7,8,9,…..}
  • Whole Numbers = {0,1,2,3,4,5,7,8,9,….}

Check out the difference between natural and whole numbers to know more about the differentiating properties of these two sets of numbers.

Natural Numbers and Whole Numbers Set Representation

The above representation of sets shows two regions. A ∩ B i.e. intersection of natural numbers and whole numbers (1, 2, 3, 4, 5, 6, ……..) and the green region showing A-B, i.e. part of the whole number (0).

Thus, a whole number is “a part of Integers consisting of all the natural number including 0.”

Is ‘0’ a Natural Number?

The answer to this question is ‘No’. As we know already, natural numbers start with 1 to infinity and are positive integers. But when we combine 0 with a positive integer such as 10, 20, etc. it becomes a natural number. In fact, 0 is a whole number which has a null value.

Every Natural Number is a Whole Number. True or False?

Every natural number is a whole number. The statement is true because natural numbers are the positive integers that start from 1 and goes till infinity whereas whole numbers also include all the positive integers along with 0.

Representing Natural Numbers on a Number Line

Natural numbers representation on a number line is as follows:

Natural Numbers and Whole numbers on a Number line

The above number line represents natural numbers and whole numbers. All the integers on the right-hand side of 0 represent the natural numbers, thus forming an infinite set of numbers. When 0 is included, these numbers become whole numbers which are also an infinite set of numbers.

Set of Natural Numbers

In a set notation, the symbol of natural number is “N” and it is represented as given below.

N = Set of all numbers starting from 1.

In Roster Form:

N = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ………………………………}

In Set Builder Form:

N = {x : x is an integer starting from 1}

Natural Numbers Examples

The natural numbers include the positive integers (also known as non-negative integers) and a few examples include 1, 2, 3, 4, 5, 6, …∞.  In other words, natural numbers are a set of all the whole numbers excluding 0.

23, 56, 78, 999, 100202, etc. are all examples of natural numbers.

Properties of Natural Numbers

Natural numbers properties are segregated into four main properties which include:

  • Closure property
  • Commutative property
  • Associative property
  • Distributive property 

Each of these properties is explained below in detail.

Closure Property

Natural numbers are always closed under addition and multiplication. The addition and multiplication of two or more natural numbers will always yield a natural number. In the case of subtraction and division, natural numbers do not obey closure property, which means subtracting or dividing two natural numbers might not give a natural number as a result.

  • Addition: 1 + 2 = 3, 3 + 4 = 7, etc. In each of these cases, the resulting number is always a natural number.
  • Multiplication: 2 × 3 = 6, 5 × 4 = 20, etc. In this case also, the resultant is always a natural number.
  • Subtraction: 9 – 5 = 4, 3 – 5 = -2, etc. In this case, the result may or may not be a natural number.
  • Division: 10 ÷ 5 = 2, 10 ÷ 3 = 3.33, etc. In this case, also, the resultant number may or may not be a natural number.

Note: Closure property does not hold, if any of the numbers in case of multiplication and division, is not a natural number. But for addition and subtraction, if the result is a positive number, then only closure property exists.

For example: 

  • -2 x 3 = -6; Not a natural number
  • 6/-2 = -3; Not a natural number
  • Associative Property

The associative property holds true in case of addition and multiplication of natural numbers i.e. a + ( b + c ) = ( a + b ) + c and a × ( b × c ) = ( a × b ) × c. On the other hand, for subtraction and division of natural numbers, the associative property does not hold true . An example of this is given below.

  • Addition: a + ( b + c ) = ( a + b ) + c => 3 + (15 + 1 ) = 19 and (3 + 15 ) + 1 = 19.
  • Multiplication: a × ( b × c ) = ( a × b ) × c => 3 × (15 × 1 ) = 45 and ( 3 × 15 ) × 1 = 45.
  • Subtraction: a – ( b – c ) ≠ ( a – b ) – c => 2 – (15 – 1 ) = – 12 and ( 2 – 15 ) – 1 = – 14.
  • Division: a ÷ ( b ÷ c ) ≠ ( a ÷ b ) ÷ c => 2 ÷( 3 ÷ 6 ) = 4 and ( 2 ÷ 3 ) ÷ 6 = 0.11.
  • Commutative Property

For commutative property

  • Addition and multiplication of natural numbers show the commutative property. For example, x + y = y + x and a × b = b × a
  • Subtraction and division of natural numbers do not show the commutative property. For example, x – y ≠ y – x and x ÷ y ≠ y ÷ x
  • Distributive Property
  • Multiplication of natural numbers is always distributive over addition. For example, a × (b + c) = ab + ac
  • Multiplication of natural numbers is also distributive over subtraction. For example, a × (b – c) = ab – ac

Natural numbers are the positive integers or non-negative integers which start from 1 and ends at infinity, such as:

1,2,3,4,5,6,7,8,9,10,……,∞.

Is 0 a Natural Number?

Zero does not have a positive or negative value. Since all the natural numbers are positive integers, hence we cannot say zero is a natural number. Although zero is called a whole number.

What are the first ten Natural Numbers?

The first ten natural numbers are: 1,2,3,4,5,6,7,8,9, and 10.

What is the difference between Natural numbers and Whole numbers?

Natural numbers include only positive integers and starts from 1 till infinity. Whereas whole numbers are the combination of zero and natural numbers, as it starts from 0 and ends at infinite value.

What are the examples of Natural numbers?

The examples of natural numbers are 5, 7, 21, 24, 99, 101, etc.

Decimal Representation of Rational Numbers: Definition, Types, Facts

What is the decimal representation of rational numbers, writing rational numbers in the decimal form, decimal form of a rational number chart, solved examples on decimal representation of rational numbers, practice problems on decimal representation of rational numbers, frequently asked questions on decimal representation of rational numbers.

Decimal representation of rational numbers is a method of finding decimal expansion of the given rational number or converting a rational number into an equivalent decimal number using long division.  

Decimal form of a rational number example: $\frac{5}{4} = 5\div4= 1.25$

Rational numbers are the numbers of the form $\frac{p}{q}$, where p and q are integers and $q\neq0$. Decimals are the numbers that have a whole number part and a fractional part separated by a decimal point. Every rational number is either a terminating or repeating decimal.

Add 1-Digit Numbers Game

To convert the rational number $\frac{p}{q}$ into a decimal, we divide the number p by the number q using the long division process. Writing rational numbers in decimal form involves two cases. The decimal form of a rational number we get can be of 2 types:

  • When Remainder $= 0$ , the decimal expansion is terminating.  

Terminating decimal is the decimal number in which there is an end-digit. There are a finite number of digits after the decimal point. 

For example, if we divide 5 by 1, we get 0.2. The number terminates and doesn’t continue after 2. So, it’s a terminating number.

  • When Remainder $\neq0$ , the decimal expansion is non-terminating and repeating.

In a non-terminating and repeating decimal, a single digit or a block of digits repeat themselves infinitely after the decimal point. 

For example, we get $0.\overline{09}=0.09090909$ … on dividing 1 by 11. Here, the group of digits, 09, keep on repeating. 

So, how are rational numbers written as decimals? Let’s discuss both the cases.

When the decimal expansion of $\frac{p}{q}$, $q\neq 0$ comes to an end after a finite number of digits, the decimal expansion is called terminating. In this case, when we divide p by q using the long division method, we get remainder 0.

Example 1: Find the decimal representation of the rational number $\frac{4}{5}$ .

Decimal representation of 45using long division

Thus, $\frac{4}{5} = 0.8$ … terminating decimal expansion

Example 2: Find the decimal representation of the rational number $\frac{3}{4}$.

Here, $\frac{3}{4} = 0.75$ … terminating decimal expansion

Non-terminating and Repeating Decimal Representation of Rational Numbers

In some cases, when we divide p by q to find the decimal expansion of $\frac{p}{q}$, $q\neq 0$, the remainder never becomes 0. Also, the remainder repeats after some steps, which results in a non-terminating and recurring decimal expansion.

Example 1: $\frac{10}{3} = 3.333$…

What cannot be the decimal representation of a rational number?

A rational number cannot have a non-terminating and non-repeating decimal expansion.

What is the difference between rational numbers and fractions?

Rational numbers are the numbers of the form $\frac{p}{q}$, where $p$ and $q$ are integers and $q\neq0$. Fractions represent part of a whole. A fraction is written in the form of $\frac{a}{b}$, where $b\neq0$ and a & b are natural numbers. Here, “a” is the numerator that represents the number of parts taken and “b” is the denominator that represents the total number of parts of the whole.

1.6: The Base b Representation of n

  • Last updated
  • Save as PDF
  • Page ID 83340

  • Mike Barrus & W. Edwin Clark
  • University of Rhode Island

In this chapter we show how the Division Algorithm is related to a concept touched on since grade school mathematics.

Definition \(\PageIndex{1}\): Decimal Representation

Recall that the decimal representation of a positive integer \(a\) is given by \(a =a_{n-1}a_{n-2}\cdots a_1a_0\) where \[\label{decimalrep} a = a_{n-1}10^{n-1} + a_{n-2}10^{n-2} + \cdots + a_110 + a_0\] and the digits \(a_{n-1},a_{n-2},\dots,a_1,a_0\) are in the set \(\{0,1,2,3,4,5,6,7,8,9\}\) with \(a_{n-1}\neq 0\) . In this case we say that the integer \(a\) is an \(n\) -digit number or that \(a\) is \(n\) digits long.

For example, the numerals in “682” are understood to mean six hundred eighty-two, because the locations of 6, 8, and 2 (in the “hundreds’ place”, “tens’ place”, and “ones’ place”) indicate the number \(6 \cdot 100 + 8\cdot 10 + 2\) .

In this chapter we will justify the claim that every positive integer has a decimal representation. However, we will do so in a more general setting.

Definition \(\PageIndex{2}\): Base \(b\) Representation of \(n\)

Let \(b\ge 2\) and \(n>0\) . We write \[\label{eq:base} n=\left[a_k,a_{k-1},\dotsc,a_1,a_0\right]_b\] if and only if for some \(k\ge 0\) \[n=a_kb^k+a_{k-1}b^{k-1}+\dotsb+a_1b+a_0\nonumber \] where \(a_i\in\{0,1,\dotsc,b-1\}\) for \(i=0,1,\dotsc,k\) . \(\left[a_k,a_{k-1},\dotsc,a_1,a_0\right]\) is called a base \(b\) representation of \(n\) .

Remark \(\PageIndex{1}\)

Base \(b\) is referred to as \[\begin{aligned} binary\quad & \text{if }b=2, \\ ternary\quad & \text{if }b=3, \\ octal\quad & \text{if }b=8, \\ decimal\quad & \text{if }b=10, \\ hexadecimal\quad & \text{if }b=16.\end{aligned}\] If \(b\) is understood, especially if \(b=10\) , we write \(a_ka_{k-1}\dotsm a_1a_0\) in place of \(\left[a_k,a_{k-1},\dotsc,a_1,a_0\right]_{b}\) . In the case of \(b=16\) , which is used frequently in computer science, the “digits” \(10\) , \(11\) , \(12\) , \(13\) , \(14\) and \(15\) are replaced by \(A\) , \(B\) , \(C\) , \(D\) , \(E\) and \(F\) , respectively.

For a fixed base \(b\ge 2\) , the numbers \(a_i\in\{0,1,2,\dotsc,b-1\}\) in equation \(\eqref{eq:base}\) are called the digits of the base \(b\) representation of \(n\) . In the binary case \(a_i\in\{0,1\}\) and the \(a_i\) ’s are called bits ( bi nary digi ts ).

Here are a few examples:

  • \(267=[5,3,1]_7\) since \(267 = 5 \cdot 7^2+3\cdot 7 +1\) .
  • \(147=[1,0,0,1,0,0,1,1]_2\) since \(147=1\cdot 2^7+0\cdot 2^6+0\cdot 2^5+1\cdot 2^4+0\cdot 2^3+0\cdot 2^2+1\cdot 2+1\) .
  • \(4879=[4,8,7,9]_{10}\) since \(4879 = 4\cdot 10^3+8\cdot 10^2 + 7\cdot 10 + 9\) .
  • \(10705679=[A,3,5,B,0,F]_{16}\) since \(10705679=10\cdot 16^5+3\cdot 16^4+5\cdot 16^3+11\cdot 16^2+0\cdot 16+15\) .
  • \(107056791=[107, 56, 791]_{1000}\) since \(107056791=107\cdot 1000^2+56\cdot 1000 +791\) .

Theorem \(\PageIndex{1}\): Base \(b\) Representation

If \(b\ge 2\) , then every \(n>0\) has a unique base \(b\) representation of the form \(n=\left[a_k,\dotsc,a_1,a_0\right]_b\) with \(a_k>0\) .

Apply repeatedly the Division Algorithm as follows: \[\begin{aligned} n &=bq_0+r_0,\quad 0\le r_0<b \\ q_0 &=bq_1+r_1,\quad 0\le r_1<b \\ q_1 &=bq_2+r_2,\quad 0\le r_2<b \\ &\qquad\vdots \\ q_{k-1} &=bq_k+r_k,\quad 0\le r_k<b \\ q_k &=bq_{k+1}+r_{k+1},\quad 0\le r_{k+1}<b.\end{aligned}\] Note that in every step we always divide by \(b\) . In the first line, we divide \(n\) by \(b\) , and then in each line after the first, what we divide by \(b\) is the quotient of the previous line; we then use the resulting quotient for the next line.

From the repeated division it is not difficult to see that as long as \(q_k>0\) , it is true that \[n>q_0>q_1>\dotsm>q_k.\nonumber \] Since this cannot go on forever we eventually obtain \(q_\ell=0\) for some \(\ell\) . Then we have \[q_{\ell-1}=b\cdot 0+r_\ell.\nonumber \] We claim that \(n=\left[r_\ell,r_{\ell-1},\dotsc,r_0\right]_b\) if \(\ell\) is the smallest integer such that \(q_\ell=0\) . To see this, note that \[n=bq_0+r_0\nonumber \] and \[q_0=bq_1+r_1.\nonumber \] Hence \[\begin{aligned} n &=b\left(bq_1+r_1\right)+r_0 \\ n &=b^2q_1+br_1+r_0.\end{aligned}\] Continuing in this way we find that \[n=b^{\ell+1}q_{\ell}+b^\ell r_\ell+\dotsb+br_1+r_0.\nonumber \] And, since \(q_\ell=0\) we have \[\label{eq: base b again} n=b^\ell r_\ell+\dotsb+br_1+r_0,\] which shows that \[n=\left[r_\ell,\dotsc,r_1,r_0\right]_b.\nonumber \] To see that this representation is unique, note that from equation \(\eqref{eq: base b again}\) we have \[n=b\left(b^{\ell-1}r_\ell+\dotsb+r_1\right)+r_0,\quad 0\le r_0<b.\nonumber \] By the Division Algorithm it follows that \(r_0\) is uniquely determined by \(n\) , as is the quotient \(q=b^{\ell-1}r_\ell+\dotsb+r_1\) . A similar argument shows that \(r_1\) is uniquely determined. Continuing in this way we see that all the digits \(r_\ell,r_{\ell-1},\dotsc,r_0\) are uniquely determined.

Example \(\PageIndex{1}\): Base Conversions

We can use the idea from the proof of Theorem \(\PageIndex{1}\) , repeated applications of the Division Algorithm, to express numbers in an an arbitrary base. Following are some examples.

  • We find the base \(7\) representation of \(1\) , \(749\) . \[\begin{aligned} 1749 &=249\cdot 7+6 \\ 249 &=35\cdot 7+4 \\ 35 &=5\cdot 7+0 \\ 5 &=0\cdot 7+5\end{aligned}\] Hence \(1749=[5,0,4,6]_7\) .
  • We find the base \(12\) representation of \(19\) , \(151\) . \[\begin{aligned} 19,151 &=1595\cdot 12+11 \\ 1,595 &=132\cdot 12+11 \\ 132 &=11\cdot 12+0 \\ 11 &=0\cdot 12+11\end{aligned}\] \(\therefore 19,151=[11,0,11,11]_{12}\) .
  • Find the base \(10\) representation of \(1\) , \(203\) . \[\begin{aligned} 1203 &=120\cdot 10+3 \\ 120 &= 12\cdot 10+0 \\ 12 &=1\cdot 10+2 \\ 1 &=0\cdot 10+1\end{aligned}\] \(\therefore 1203=[1,2,0,3]_{10}\) .
  • Find the base \(2\) ( binary ) representation of \(137\) . \[\begin{aligned} 137 &=2\cdot 68+1 \\ 68 &=2\cdot 34+0 \\ 34 &=2\cdot 17+0 \\ 17 &=2\cdot 8+1 \\ 8 &=2\cdot 4+0 \\ 4 &=2\cdot 2+0 \\ 2 &=2\cdot 1+0 \\ 1 &=2\cdot 0+1\end{aligned}\] \(\therefore 137=[1,0,0,0,1,0,0,1]_2\) .

Remark \(\PageIndex{2}\)

To find the binary representation of a small number, the following method is often easier than the above method:

Given \(n>0\) let \(2^{n_1}\) be the largest power of \(2\) satisfying \(2^{n_1}\le n\) . Let \(2^{n_2}\) be the largest power of \(2\) satisfying \[2^{n_2}\le n-2^{n_1}.\nonumber \] Let \(2^{n_3}\) be the largest power of \(2\) satisfying \[2^{n_3}\le n-2^{n_1}-2^{n_2}.\nonumber \] Note that at this point we have \[0\le n-\left(2^{n_1}+2^{n_2}+2^{n_3}\right)<n-\left(2^{n_1}+2^{n_2}\right)<n-2^{n_1}<n.\nonumber \] Continuing in this way, eventually we get \[0=n-\left(2^{n_1}+2^{n_2}+\dotsb+2^{n_k}\right).\nonumber \] Then \(n=2^{n_1}+2^{n_2}+\dotsb+2^{n_k}\) , and this gives the binary representation of \(n\) .

Example \(\PageIndex{2}\)

Take \(n=137\) . Note that \(2^1=2\) , \(2^2=4\) , \(2^3=8\) , \(2^4=16\) , \(2^5=32\) , \(2^6=64\) , \(2^7=128\) , and \(2^8=256\) . Using the above method we compute: \[\begin{aligned} 137-2^7 &=137-128=9, \\ 9-2^3 &=1, \\ 1-2^0 &=0.\end{aligned}\] So we have \[\begin{gathered} 137=2^7+9=2^7+2^3+1, \\ \therefore 137=2^7+0\cdot2^6+0\cdot2^5+0\cdot2^4+2^3+0\cdot2^2+0\cdot 2+1.\end{gathered}\] So \(137=[1,0,0,0,1,0,0,1]_2\) .

Exercise \(\PageIndex{1}\)

Generalize the following observations \[\begin{aligned} 1 &=[1]_2 \\ 3 &=[1,1]_2 \\ 7 &=[1,1,1]_2 \\ 15 &=[1,1,1,1]_2 \\ 31 &=[1,1,1,1,1]_2 \\ 63 &=[1,1,1,1,1,1]_2\end{aligned}\] by noticing a pattern in the numbers on the left-hand sides and conjecturing a formula for the number that has \(n\) 1’s in its binary representation. Prove your generalization.

(Hint: See Exercise 1.3.8 .)

Exercise \(\PageIndex{2}\)

Generalize the following observation: \[\begin{aligned} 2 &=[2]_3\\ 8 &=[2,2]_3 \\ 26 &=[2,2,2]_3 \\ 80 &=[2,2,2,2]_3 \\ 242 &=[2,2,2,2,2]_3\end{aligned}\] by noticing a pattern in the numbers on the left-hand sides and conjecturing a formula for the number that has \(n\) 2’s in its ternary representation. Prove your generalization.

Exercise \(\PageIndex{3}\)

Generalize Exercises \(\PageIndex{1}\) and \(\PageIndex{2}\) to an arbitrary base \(b\ge 2\) .

Exercise \(\PageIndex{4}\)

Show how to use both methods to find the binary representation of \(455\) .

Exercise \(\PageIndex{5}\)

Make a vertical list of the binary representation of the integers 1 to 16.

Exercise \(\PageIndex{6}\)

Find the decimal representation of each of the following numbers.

  • \([5,3,6,2]_7\) ;
  • hexadecimal numbers FEEDAFACE and BADBEEF.

Exercise \(\PageIndex{7}\)

Following the technique of Example \(\PageIndex{1}\) , find the representations of 12345 in (i) base 3 and (ii) base 8. For both parts (i) and (ii), show your work with the same level of detail as Example \(\PageIndex{1}\) .

Exercise \(\PageIndex{8}\)

Find the base-7 representation of the number \([1,2,3,4,5,6,7,8]_9\) .

Exercise \(\PageIndex{9}\)

Prove that if \(a\in\mathbb{N}\) is an \(n\) -digit number, then \(n={\mbox{\) (a) \(}}+1\) . Here \(\log\) means logarithm to base 10. Thus \({\mbox{\) (a) \(}}+1\) is a formula for the number of digits in \(a\) .

(Hint: to prove the equation, show that if equation \(\eqref{decimalrep}\) holds with \(a_{n-1}\neq 0\) then \(10^{n-1}\le a<10^n\) . Then apply the \(\log\) to all terms of this inequality. This is allowed since \(\log\) is an increasing function on the set of positive real numbers.)

Exercise \(\PageIndex{10}\)

Use the previous exercise to determine the number of digits in the decimal representation of the number \(2^{3321928}\) .

(Hint: recall that \(\log(x^y)=y\log(x)\) when \(x\) and \(y\) are positive.)

Exercise \(\PageIndex{11}\)

Recall that \(\log_b(a)\) means the logarithm of \(a\) with base \(b\) . Can you adapt the ideas from Exercise \(\PageIndex{9}\) to find a formula for the number of digits in the base \(b\) representation of \(a\) ?
