Ok, so I have 2x^2 and into the 'x' I want to put the value -3. Would the correct way to do this be 2*-3=-6 and then square it to get 36? Or would it be -3^2=9 and then 9*2=18?  Which way is correct?

Order of operations is 

parenthesis

exponents

multiplication and division 

addition and subtraction

You would do the exponent before the multiplication, so -3^2 = 9, and then 2*9 = 18.
