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=3d7ba2e5a4c29aa7c9f11cb559d9372c.png\")
![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=d56ca6d87b995687ac61a80574961b15.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.
\![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=3b1140829df2f3275638c7f216cb0279.png\")
(Add the numbers in the numerator)
![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=d2bb51b4f8ba5fe72ed619a72d965197.png\")
(Subtract numbers in the denominator![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=dd76a2a264de5b62af9135db1a14ffe4.png\")
)![\"\"](\"/userfiles/image/steps_images/step2.JPG\")
Next operation is division.

(Divide: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=83ae79930925bd15828ea2a99ffea20e.png\")
)![\"\"](\"/userfiles/image/steps_images/solution.JPG\")
The value of the expression is 2.
