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"

\

\"\"

\

The expression is \"\".

\

Substitute x = 4,and y = 3 in the expression.

\

\"\".                 (Substitute x = 4,and y = 3)

\

Simplify the expression using order of operations (PEMDAS).

\

First evaluate the expression within the parentheses.

\

First operation is evaluate powers.

\

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

\

Next operation is multiplication.

\

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

\

Next operation is subtraction.

\

\"\"                                      (Subtract: \"\")

\

Next operation is multiplication.

\

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

\

The value of the expression is 7.
