#### Explanation:

The most important starting point is to identify the number of different terms. Each term simplifies to a single answer which can be added or subtracted in the last step.

$\text{ "color(green)(17)" "+" "color(blue)(4)" "-" "color(red)(28div4)" }$has $3$ terms

$\text{ "color(green)(17)" "+" "color(blue)(4)" "-" } \textcolor{red}{7}$

$= 21 - 7$

$= 14$
