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=08b9d7061cfafe02c72d00b1a016d220.png\")
In the given expression there are no grouping symbols. So, next operation is multiplication.

(Multiply: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=58c2d3ca025fd116b26e554d84812521.png\")
)![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
Next operation is addition.
