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=10c558407c4b8f8db19c0dc7298b3c75.png\")
![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=20930d61fb7f8ceff370307838a04b56.png\")
(Replace y with 3 and z with 9 in original expression)

(Rewrite the expression as division problem)![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
First evaluate the expression within the parenthesis.
\![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=5bbae5dab55fb33a5d7551f605b001aa.png\")
(Multiply: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=2c559aa930a76fab7c9f3ca79376ca76.png\")
)
Next operation is division.

(Divide: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=6627d4dcc929819cc308c90c24c71c20.png\")
)![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The value of the expression is 2.
