32

Explanation:

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

color(magenta)(23)color(blue)(-12 div4 xx2) color(red)( +15)

=color(magenta)(23)color(blue)(-12/4 xx2) color(red)( +15)

=color(magenta)(23)color(blue)(-3xx2) color(red)( +15)

=color(magenta)(23)color(blue)(-6) color(red)( +15)

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

=color(magenta)(23) color(red)(+15)color(blue)(-6)

=32
