$32$

#### Explanation:

There are 3 terms. work out each one separately and and the single answers in the last step.

$\textcolor{m a \ge n t a}{23} \textcolor{b l u e}{- 12 \div 4 \times 2} \textcolor{red}{+ 15}$

=$\textcolor{m a \ge n t a}{23} \textcolor{b l u e}{- \frac{12}{4} \times 2} \textcolor{red}{+ 15}$

=$\textcolor{m a \ge n t a}{23} \textcolor{b l u e}{- 3 \times 2} \textcolor{red}{+ 15}$

=$\textcolor{m a \ge n t a}{23} \textcolor{b l u e}{- 6} \textcolor{red}{+ 15}$

To avoid confusion, write all the additions at the beginning, then the subtractions:

=$\textcolor{m a \ge n t a}{23} \textcolor{red}{+ 15} \textcolor{b l u e}{- 6}$
