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=8f0ac125c1ea92ce58018f328c2bb19d.png\")

(Substitute ![\"\"](\"plugins/fckeditor_wiris/integration/showimage.php?formula=940cbc72cc388525a531d893965f833c.png\")
)
Simplify the expression uisng order of operations (PEMDAS).
\Since there are no parentheses and powers, first operation is multiplication.
