How many whole numbers are there between 1 and 100?

Whole numbers is a group of natural numbers or counting numbers including the number zero. All the numbers in the range from 1 to 100 are Whole numbers. There are a total of 100 numbers between 1 to 100.

In this article, we will learn more about whole numbers from 1 to 100, their sum, average, and others.

Whole Number

The counting numbers including 0 are known as whole numbers. We know that the numbers 1, 2, 3, 4, 5, … etc. are the counting numbers, and the numbers 0, 1, 2, 3, 4, 5, 6, … etc are the whole numbers. Whole numbers are denoted as W and Natural numbers are denoted as N. Therefore, we can represent whole numbers as,

• W = {0, 1, 2, 3, 4, 5, ….}
• W= {N} + 0

We can easily represent the whole numbers on the number line and the on the right side of 0 (including 0) in the number line are whole numbers.

The image added below shows the whole number on the number line.

List of Whole Numbers from 1 to 100

All the numbers from 0 to infinity are whole numbers, while counting whole numbers between 1 and 100, no numbers are left out and all the numbers are considered whole numbers. There are a total of 100 whole numbers from 1 to 100. In this list, the smallest whole number is 1 and the largest whole number is 100.

The list containing all the numbers from 1 to 100 is,

Sum of Whole Numbers from 1 to 100

We know that whole numbers from 1 to 100 are, 1, 2, 3, 4, 5, ….., 100. All the numbers in this list are in AP and their common difference is 1 and the first and the last term are 1 and 100 respectively. Using all this information we can easily get the sum of all the whole numbers from 1 to 100. For calculating the sum of,

S = 1+2+3+4+5+…..+100

First Term (a) = 1

Common Diference (d) = 1

Last Term (l) = l

Using the sum of the AP formula,

S = n/2[a + l]

S = 100/2 [1 + 100]

S = 50[101]

S = 5050

Thus, the sum of whole numbers from 1 to 100 is 5050.

Average of Whole Numbers from 1 to 100

Now after finding the sum of the whole numbers from 1 to 100, we can easily find the average of the whole numbers from 1 to 100 using the average formula as,

Average = (Sum of Terms)/(Number of Terms)

From the above heading, we know that the sum of whole numbers from 1 to 100 is 5050.

The number of whole numbers from 1 to 100 is 100.

Now using the average formula,

A = 5050/100

A = 50.5

Thus, the average of all whole numbers from 1 to 100 is 50.5

Operations on Whole Numbers

We can perform various operations on the whole number including,

• Addition of Whole Number
• Subtraction of Whole Number
• Multiplication of Whole Number
• Division of Whole Number

Now let’s learn about them in detail.

Addition of Whole Number

We can simply perform addition on whole numbers and the addition of a whole number represents a whole number. This can be better understood with the example discussed below,

Example: Find the sum of 27 + 11

Solution:

Given,

= 27 + 11

As both the numbers are whole numbers their addition is also a whole number. Finding their sum.

= 38 (whole number)

This is the required sum.

Subtraction of Whole Number

We can simply perform subtraction on whole numbers and the subtraction of a whole number may or may not represents a whole number. This can be better understood with the example discussed below,

Example: Find the difference, between 27 – 11 and 11 – 27

Solution:

Given,

= 27 – 11

As both the numbers are whole numbers their subtraction may or may not results in a whole number.

= 16 (whole number)

This is the required difference.

Given,

= 11 – 27

= -16 (Integer)

This is the required difference.

Multiplication of Whole Number

We can simply perform multiplication on whole numbers and the multiplication of a whole number represents a whole number. This can be better understood with the example discussed below,

Example: Find the product of 27 × 11

Solution:

Given,

= 27 × 11

As both the numbers are whole numbers their multiplication is also a whole number. Finding their product.

= 297 (whole number)

This is the required product.

Division of Whole Number

We can simply perform division on whole numbers and the division of a whole number may or may not result in a whole number. This can be better understood with the example discussed below,

Example: Solve

• 27 / 11
• 27 / 9

Solution:

Given,

= 27 / 11

Dividing them,

= 2.4545 (Decimal)

Now,

Given,

= 27 / 9

Dividing them,

= 3 (Whole Number)

Solved Examples on Whole Number

Example 1: Find the sum of 34 + 45

Solution:

Given,

= 34 + 45

As both the numbers are whole numbers their addition is also a whole number. Finding their sum.

= 79 (whole number)

This is the required sum.

Example 2: Find the difference 89 – 67.

Solution:

Given,

= 89 – 67

= 23 (whole number)

This is the required difference.

Example 3: Find the product of 7 × 3

Solution:

Given,

= 7 × 3

As both the numbers are whole numbers their multiplication is also a whole number. Finding their product.

= 21 (whole number)

This is the required product.

Example 4: Solve, 48 / 4

Solution:

Given,

= 48 / 4

Dividing them,

= 12 (Whole Number)
