Question

To simplify the expression −14+73+27+(−11) , Corey began by rewriting it as (73+27)+(−14+(−11)) . Which properties did Corey use to rewrite the expression? Select all that apply. A) Identity Property cross out B) Distributive Property cross out C) Additive Inverse Property cross out D) Associative Property of Addition cross out E) Commutative Property of Addition

Answer 1

Corey utilized the Associative Property of Addition (grouping numbers differently) and the Commutative Property of Addition (changing the order of numbers) when rewriting the expression.

the correct answer is D

Step-by-step explanation:

When Corey rewrote the expression −14+73+27+(−11) as (73+27)+(−14+(−11)), he made use of two mathematical properties: the Associative Property of Addition and the Commutative Property of Addition.

The Associative Property allows us to regroup the numbers without changing the result, while the Commutative Property lets us rearrange the addends in any order. Therefore, the properties Corey used are:

Associative Property of Addition (D)

Commutative Property of Addition (E)
