#=40#

Explanation:

Always count the number of terms first. There are 3 terms. Keep them separate until each has been simplified to a single answer. In this case there is only one term which needs simplifying.

#color(blue)(36)color(red)(-4div2)color(purple)( +6)#

#=color(blue)(36)color(red)(-2)color(purple)( +6)#

To avoid errors in which terms are being subtracted, it is safer to place the adds at the beginning and the subtracts at the end.

#=color(blue)(36)color(purple)( +6) color(red)(-2)#

#=40#
