Properties of Whole Numbers - Commutativity Property of Whole Number

Notes

Commutative Property of Whole Numbers:

In both cases, we reach 8. 5 + 3 is the same as 3 + 5.
You can add two whole numbers in any order.
We say that addition is commutative for whole numbers. This property is known as the Commutativity of addition.

2. Commutativity of multiplication:

You will observe that 3 × 4 = 4 × 3.
You can multiply two whole numbers in any order.
We say multiplication is commutative for whole numbers.

3. Commutativity of Subtraction:

a - b ≠ b - a
a = 3, b = 5
a - b = b - a
3 - 5 = 5 - 3
- 2 ≠ 2

Thus, Subtraction is not commutative for whole numbers.

4. Commutativity of Division:

a ÷ b ≠ b ÷ a
a = 9 and b = 3

9/3 = 3/9

3 ≠ 0.333.

Thus, Division is not commutative for whole numbers.
