can sumbody help me with the steps to this math problem?

Evaluate: 9 + (8-2)^2 x 20 / 5

• math -

9 + (8-2)^2 x 20 / 5

9 + 36 * 20/5
9 + 36 * 4 = ??

• math -

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

• math -

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