Question

Definition of the identity property of addition and the commutative property of addition

Answer 1

The identity property of addition states that if we add zero to any number, then the sum is equal to the original number.

For example, the identity property tells us that 5 + 0 = 5.

In general terms, the identity property of addition can be written as followed.

a + 0 = a

This means that "a" is a variable that represents any number.

The commutative property of addition states that changing the order of the addends does not affect the sum.

For example, 2 + 3 = 3 + 2.

No madder what side we do, they both equal 5.

Answer 2

Let x, y be numbers.
The addition identity property states that 0 + x = x.
The commutative property states that x + y = y + x
