1: How could you rewrite the expression (-3+5)+8+(-1) using the Associative Property of Addition?

Question

A- -3-8+(5+1)
B- (-3+(-1))+(5+8)
C- -3(5+8)+(-1)
D- 5+8+3+1
2: Which property is represented by 5+(-8)=-8+5?
A- Identity
B- Associative
C- Commutative
D- Distributive

Answer 1

#1 None of the above
The Associative Property property says that
(a+b)+c = a+(b+c)
That is, you can move the parentheses around, but you don't change the ordering of the numbers.
A and B might be candidates, but they also switch things around, which is using the Commutative Property.

#2. So, as noted above, choice C is the correct one here.
