Order of Operations:
\To simplify the expression follow the order of operations: (PEMDAS)
\1. Evaluate the expressions inside the Parenthesis/Brackets (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"
The expression is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=3e9fac3c2f96873d6714458a2bfcb27e.png\")
![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=d7e113bb8a97ef7554849d2ddc6c7934.png\")
(Rewrite the expression as division problem)
According order of operations inside the grouping symbols should be evaluated first.
\First operation is evaluating expression within the parentheses.

(Subtract the numbers in the numerator: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=fc74362a760a573bc9e9f203804b78e8.png\")

Next operation is division.
