Order of Operations (PEMDAS):
\To simplify the expression follow the order of operations:
\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=ace7de26bdb6e4f108e7981fcd30c19d.png\")
According order of operations inside the grouping symbols should be evaluated first.
\First operation is subtracting the numbers within the parenthesis.
