3-27.

1. $(−4)(−2)−6(2−5)$

Circle the terms.

Simplify within the circled terms.

Circle the terms again. Then simplify and repeat.

$\enclose{circle}[mathcolor="blue"]{\color{black}{\left(-4\right)\left(-2\right)}}-\enclose{circle}[mathcolor="blue"]{\color{black}{6\left(2-5\right)}}$

$8−6(−3)$

$\enclose{circle}[mathcolor="blue"]{\color{black}{8}}-\enclose{circle}[mathcolor="blue"]{\color{black}{6\left(-3\right)}}$

$26$

1. $23−(17−3·4)^2+6$

For parts (b), (c), and (d) follow the strategy outlined in part (a).

1. $14(2+3−2·2)\div(4^2−3^2)$

$2$

1. $12.7−18.5+15+6.3−1+28.5$
