1-21.

Calculate the value of each of the following expressions.

1. $\frac { 3 ^ { 2 } + 2 \cdot 8 } { 16 - 11 }$

• Review the Order of Operations in the glossary if you need help remembering it.

Evaluate the numerator and the denominator separately using the Order of Operations.

1. $( 32 \cdot \frac { 1 } { 2 } + 6 ) - ( 4 - 1 )$

• $(16 + 6) − (3)$
$22 − 3$
$19$

1. $4 ( ( 8 - 10 \cdot 3 ) + 2 ^ { 3 } - 5 )$

• Evaluate the expression within the innermost parentheses first. Continue evaluating the resulting expression.
