Order of Operations:
\To simplify the expression follow the order of operations: (PEMDAS)
\1. Evaluate the expressions inside the Parentheses/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=2b9e71a1dc1053d2267788d2ab903fa9.png\")
