2.
25 + (–15 + 4) = (25 + (–15)) + 4
3.

Answer 1

1234 is column a and abc is column b

Answer 2

okay do you know what the properties look like?

Answer 3

no

Answer 4

okay so the commutative property is:

a + b = b + a

Answer 5

associative property:

a+(b+c)=(a+b)+c

Answer 6

thats 2 properties shown, you see any matches?

Answer 7

no

Answer 8

help
im bad at math

Answer 9

its all good man.... dont worry.. well lets do commutative first.

so a+b=b+a...

-30+(-16)=-16+(-30)

i did the first one... now you try and find the associative property..

Answer 10

so if the associative property is:

a+(b+c)=(a+b)+c

Answer 11
