A simple technique for remembering the order of operations is turned into phrase

The expression is .

                (Substitute x = 7)

First operation is multiplication.

                   (Multiply: )

Rewrite the improper fraction  as a mixed number.

Begin by dividing 67 by 22. The remainder will be the numerator of the mixed number’s fraction.

              (Factor 67:   and remainder is 1)

The value of the expression is .
