Question 147602: Hi,
I am attempting to solve an equation with parentheses inside of brackets. The problems are similar to 9[-7-(77-43)]
I know to solve the parenthases first so I have and I can chane the signs of the terms by doing the following:
9[-70+(-77+43)]
9[-70+34]
9[-36]
-324
This answer seems incorrect but I am unsure where I went wrong. Can you help?
Thank you very much.
