The expression is ![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=9911ec292814408dd319bddf1f3857ee.png\")
.
To simplify the expression follow the order of operations:
\1. Evaluate the expressions inside grouping symbols.
\2. Evaluate powers
\3. Multiply and/or Divide in order from left to right.
\4. Add and/or Subtract in order from left to right
\ \\
A simple technique for remembering the order pf operations is turned into phrase
\“Please Excuse My Dear Aunty Sally”![\"\"](\"/userfiles/image/steps_images/step2.JPG\")
First operation is multiplication.
\![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=4c9accd4fe4f77c313a827214b9c3baa.png\")
(Multiply: ![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=614a43744cf3a0fe7a88259e67a9953d.png\")
)
Next operation is addition
\= 25 (Add: 9 + 16 = 25)![\"\"](\"/userfiles/image/steps_images/solution.JPG\")
The value of the expression is 25.
