Question

Describe how you know that (8+9)+3 is equivalent to 8+(9+3). What is the benefit to using this property

Answer 1

Associative property of addition

Explanation:

The associative property of addition is as follows :

a+(b+c) = (a+b)+c

We have,

a = 8, b = 9 and c = 3

So,

Using above property,

(8+9)+3 = 8+(9+3)

20 = 20

Hence, this is the required solution.
