To simplify the expression follow the order of operations: (PEMDAS)
\1. Evaluate the expressions inside Brackets/Parenthesis (P).
\2. Evaluate Powers/Exponents (E).
\3. Multiply and/or Divide in order from left to right (MD).
\4. Add and/or Subtract in order from left to right (AS).
\A simple technique for remembering the order pf operations is turned into phrase
\“Please Excuse My Dear Aunty Sally”![\"\"](\"http://c4anything.com/userfiles/image/steps_images/step2.JPG\")
According order of operations inside the grouping symbols should be
\evaluated first.
\First operation is dividing the numbers within the parenthesis.
