Order of Operations:

\
\

To simplify the expression follow the order of operations: (PEMDAS)

\

1.      Evaluate the expressions inside Brackets/Parenthesis (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 \"\".

\

\"\"               (Replace n with 4)

\

First operation is Evaluating power.

\

\"\"              (Evaluate power: \"\")

\

Next operation is Multiplication.

\

\"\"                    (Multiply: \"\")

\

Next operation is Division.

\

\"\"                      (Divide: \"\")

\

Next operation is Addition.

\

 \"\"                           (Add: \"\")\"\"

\

The value of the expression is 14.
