$29$

#### Explanation:

There are two terms. Simplify each term to a single answer and then add or subtract the answers in the final step.

Multiplication has to be done before addition or subtraction.

$\text{ } \textcolor{b l u e}{17} + \textcolor{m a \ge n t a}{3 \times 4}$

$= \textcolor{b l u e}{17} + \textcolor{m a \ge n t a}{12}$

$= 29$

Only if there were brackets enclosing $17 + 3$ would it be done first.

$\left(17 + 3\right) \times 4$

$= 20 \times 4$

$= 80$
