Here's a good explanation of the order of operations and how to remember them -- for your future problems -- using PEMDAS as a mnemonic:

oh i thought it went like this:
9+(8-2)^2x20/5
9+6^2*20/5
9+36*20/5
9+720/5
9+144=153
u c, my math teacher told me to do it in these steps:
1)do all parantheses first
2)exponents next
3)do all multiplication and division, IN ORDER FROM LEFT TO RIGHT
4)do all addition and subtraction, IN ORDER FROM LEFT TO RIGHT
9+(8-2)^2x20/5
9+6^2*20/5
