The image below shows your first step.
Refer to the Math Notes box in this lesson if you need more help.

$16 − 5(2)$
$16 − 10 = 6$

Complete the circled areas first.

$\enclose{circle}[mathcolor="orange"]{\color{black}{31 \frac{3}{4}\cdot 4}}+\enclose{circle}[mathcolor="orange"]{\color{black}{18 \frac{5}{6}\cdot 6}}$

$127 + 113 = 240$

For parts (c) and (d), simplify what is within parentheses first. Then simplify any term with exponents. Then complete any multiplication. Finally, add or subtract the terms.
