This is not an equation the "x" means times here. Note the question is in basic math section, so it does not yet involve algebra.

First do the parantheses,

Now do exponents,

Now do multiplication,

Now you can substract,

(Note I would like to mention, "order of operations" is not a theorem, it is simply used as a definition. In order to avoid ambiguity). - Nov 29th 2006, 02:02 PMOReilly
