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”![\"\"](\"/userfiles/image/steps_images/step2.JPG\")
The first operation is subtraction
\=![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=cd5aba41eb3c07686d9d6f888d91b34b.png\")
