Question

Why might you want to use the

Answer 1

Answer :

You can use commutative property or can not be .It is not necessary to use it for given addition of integers.

Step-by-step explanation:

We are given that an expression

$-80+(-173)+(-20)$

By simplfy simply without using commutative property

$-80-173-20=-273$

Because minus minus is plus then all integers will be added.

Simplfy by using commutative property

$-80+(-173)+(-20)$

$-80+(-20)+(-173)$  (Commutative property a+b=b+a)

$-100+(-173)=-273$

The answer should not change .Hence, if you want use commutative property to change the order of the integers then answer does not effected.So, you can use it or can not be .

Answer 2

U would do this because no matter the order, the answer will be the same
