The expression is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=42a1caa29a83f7334287683880d4fc77.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 of operations is turned into phrase
\“Please Excuse My Dear Aunty Sally”![\"\"](\"/userfiles/image/steps_images/step2.JPG\")
First operation is evaluate the expressions parenthesis.

(Subtract: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=6e9c90ef79ceb24ec763f7a8ceba42bc.png\")
)

Next operation is multiplication.
\= 36 (Multiply: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c81ff2b8f41f56362c59d939a6bc0d26.png\")

![\"\"](\"/userfiles/image/steps_images/solution.JPG\")
The value of the expression is 36.
