#32#

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#
