#### Explanation:

Always count the number of terms first. For each term there must be a single answer which you will then add or subtract in the last line of working.

There are 3 terms here, so we need 3 answers

$\textcolor{b l u e}{\left(5 \times 2\right)} + \textcolor{m a \ge n t a}{\left(6 - 7\right)} + \textcolor{\mathmr{and} a n \ge}{16}$
The brackets are not necessary but they illustrate the point of 3 terms.

=$\textcolor{b l u e}{10} \textcolor{m a \ge n t a}{- 1} + \textcolor{\mathmr{and} a n \ge}{16}$

=$10 + 16 - 1 = 25$
