PEMDAS is what you need to remember. 

PEMDAS = Parentheses, exponents, multiply, division, addition, subtraction. :) That is how I remember.

So forth, you must simplify from first to last, being as parentheses are first, we do that first. But wait! We have none in this equation! So we can skip it. (: Now what's next? Exponents? Okay! So what is an exponent? An exponent is the little number next to a bigger number, which would be your 3 cubed! What is 3 cubed = to?
