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=07a7010bf77b4aaa2dfdc943cfafc847.png\")
.
![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=9e24fd52259267b4bdfa5237a8468815.png\")
(Replace c with ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=2af6e83b0e9af64878f4e8cc8c73d3f5.png\")
and a with 2)
Since there are no grouping symbols. First operation is evaluate powers.
\![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=4f90fb7035706eadaa873b840cac2d3c.png\")
(Evaluate powers: ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=f31dc15cebd3ceee130df755df05908e.png\")
)
Next operation is addition.

(Add: 9 + 4 = 13) \ \
