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"

In the given expression there are no grouping symbols.
\Simplify the expression uisng order of operations (PEMDAS).
\Since there are no parentheses and powers, first operation is multiplication.
