The expression is ![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=1217199fc20ad85365fbbf60cc045361.png\")
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

Evaluate the expression within the parenthesis i.e. subtract the numbers.
