5-83.

Evaluate each expression.

1. $10 \cdot \frac { 1 } { 2 } + ( - 6 ) ( - 3 )$

Circle the terms.

$( 10 \cdot \frac { 1 } { 2 } ) + ( - 6 ) ( - 3 )$

Do the computations and simplify.

$5 + 18 = 23$

1. $( 8 + 12 ) \div 4 - 6$

Use the same process as part (a).

$\left(8 + 12\right) ÷ 4$ is one term.

1. $\frac { - 5 + ( - 6 ) ( \frac { 2 } { 3 } ) } { - 3 }$

Compute the numerator of the fraction first.
