Which property is shown by 9 + 8 = 8 + 9?
a. commutative property of addition
Damon you looked this up too.
that rud Damon
Lol Hooman that is true xD
Commutative
The property shown by the equation 9 + 8 = 8 + 9 is the commutative property of addition.
To understand the commutative property of addition, we need to recognize that addition is a binary operation, meaning that it involves two numbers. The commutative property states that the order of the numbers being added does not affect the sum.
In this case, the equation 9 + 8 = 8 + 9 demonstrates the commutative property because it shows that regardless of the order in which we add 9 and 8, we will still get the same result.
To prove this, you can simply calculate the two sums:
9 + 8 = 17
8 + 9 = 17
As you can see, both calculations yield the same result, which confirms the commutative property of addition.
