Answer:

I think that it is #2+-3#.

Explanation:

#4-8+-3(-1+-2)#
#=4-8+(+-(-1*3)+-(+-2*3))# (Distribute #+-3# into the parentheses)
#=4-8+(+-(-3)+-(+-6))# (The #+-(-3)# really should be minus or plus 3, but Socratic can't understand the minus or plus symbol)
#=4-8+(+-(-3)+6)# (Since #+-1*+-1=1#)
#=4-8+6+-(-3)#
#=4-8+6+-3# (Since there is only no #+-# symbol now, flipping the minus or plus symbol to a #+-# symbol is okay now)
#=2+-3#
