Question

Bill claims that he found the actual December temperature by adding either -5 + 3 or 3 + −5.

What property did Bill use?
associative property
commutative property
distributive property
identity property

Answer 1

Answer: Choice B

commutative property

Reason:

The commutative property of addition is where A+B = B+A

The order of adding two items doesn't matter.

As another example: 2+7 = 9 and 7+2 = 9, so 2+7 = 7+2.

Side note: 3+ -5 is the same as 3+(-5)
