16
$7 \cdot 6 \div 2 - 4^2$

Explanation:

Step1: Solve first expression: calculate exponents

$9^2=81$, $6^2=36$

Step2: Simplify parentheses

$36+2=38$

Step3: Subtract terms in order

$81-38-1=42$

Step4: Solve second expression: calculate exponent

$4^2=16$

Step5: Do multiplication/division left to right

$7 \cdot 6=42$, $\frac{42}{2}=21$

Step6: Subtract final terms

$21-16=5$

Answer:
