How IS-5 squared equal to a plus?
This is simple. Because of BIDMAS, you do the indices first so for -5^2 you would share the five first to get 25 and then add the minus to get -25. However for -5 x -5 you would juse multiply it, and sinice a minus times a minus equals a plus, you would end up with 25.
