Order of Operations (PEMDAS):
\To simplify the expression follow the order of operations:
\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"

( 5(8) means ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=5c4ae7cc8cb7d58cd5637ab90fed3409.png\")
)
In the given expression there are no grouping symbols. First operation is multiplication.
