Rewrite as an addition expression and evaluate.

Answered by math-person
do s.o.o. which is same.opposite.opposite. so keep the 2 the same and put the opposite of the - sign and the -7. and just add them together
Answered by rebecca
so i change the - sign to + and the -7 to + 7. Then the question would look like this.
(+2)+(+7)=(+2)+(+7)
9+9 = 9+9
18 = 18
Im still a little confused. Did i do this right??
