Closure Property (Addition of Whole Numbers) : Solved Examples

Addition of Whole Numbers Addition of Integers Subtraction of Whole Numbers Subtraction of Integers Multiplication of Whole Numbers
Multiplication of Integers Division of Whole Numbers Division of Integers

Observe the following table.
First row is solved; try solving all the other rows in similar manner.
What do you understand by studying the entire table?
10 + 5 = 15 It's a whole number
24 + 78 = ? ?
123 + 456 = ? ?
33 + 100 = ? ?
9780 + 343 = ? ?
189 + 42 = ? ?
10 + 5 = 15 It's a whole number
24 + 78 = 102 It's a whole number
123 + 456 = 579 It's a whole number
33 + 100 = 133 It's a whole number
9780 + 343 = 10123 It's a whole number
189 + 42 = 231 It's a whole number


Observation
You must have observed that all the numbers in red are whole numbers. And their respective sum (which is in green) is also a whole number.
So, we get that addition of whole numbers also give us whole numbers.
And this property is known as "Closure Property of Addition of Whole Numbers"
