Order of Operations:
\To simplify the expression follow the order of operations: (PEMDAS)
\1.Evaluate the expressions inside the Parentheses/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=11a64d70fbd9b842a3edefa93dbf2037.png\")
.
Substitute the values of ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=b9770b5b4472a82c85d215ff38cd15a4.png\")
in the above expression. ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=fd991cd87beabf5f253538d1df6a4c61.png\")
First operation is multiplication in the numerator.

Next operation is division in the numerator.
\![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=66ae87bd23d77bfadf31e79d78906262.png\")
Next operation is addition in the numerator.
