Rewrite as an addition expression and evaluate.

Question

(+2)-(-7)=(+2)+(+7)
what would i do?? plz help!! thanks. :)

Answer 1

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

Answer 2

so i change the - sign to + and the -7 to + 7. Then the question would look like this.
(+2)+(+7)=(+2)+(+7)
