Which property is illustrated?15 + (5 + 7) = (15 + 5) + 7distributive propertyidentity property of additioncommutative property of additionassociative property of addition

Answer 1

When we are adding three terms, the order of the terms being added does not change the final result.

For example, in the sum 15 + 5 + 7, if we add first the 15 and 5, we have:

`(15+5)+7=20+7=27`

And if we add first the 5 and 7, we have:

`15+(5+7)=15+12=27`

This property is known as the associative property of addition.

Correct option: fourth one.
