can sumbody help me with the steps to this math problem?
Evaluate: 9 + (82)^2 x 20 / 5

9 + (82)^2 x 20 / 5
9 + 36 * 20/5
9 + 36 * 4 = ?? 
oh i thought it went like this:
9+(82)^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 
Here's a good explanation of the order of operations and how to remember them  for your future problems  using PEMDAS as a mnemonic:

my math teacher told me not to:
1)do all parantheses
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 
those are the steps i m supposed to use, i just wanted to make sure
