[4-(7-5(2-3)+2]+3[4−(7−5(2−3)+2]+3 is missing a right parenthesis. It could meaningfully go in three places. Each gives a different answer.
Case 1
[4-(7-5color(red)(")")(2-3)+2]+3" "[4−(7−5)(2−3)+2]+3 do innermost parentheses first
[4-underbrace((7-5)) underbrace((2-3))+2]+3" "
= [4-(2)(-1)+2]+3" " now multiply inside the brackets
= [4-underbrace((2)(-1))+2]+3" "
= [4-(-2)+2]+3" " now add/subtract left to right inside the brackets
= [6+2]+3 = [8]+3 = 11
Case 2
[4-(7-5(2-3)color(red)(")")+2]+3" " innermost parentheses first
[4-(7-5 underbrace((2-3)))+2]+3" "
[4-(7-5(-1))+2]+3" " now multiply -5xx-1
[4-(7+5)+2]+3" " innermost remaining parentheses
[4-12+2]+3" " add/subtract L to R in brackets
[-8+2]+3 = [-6]+3" " finish
= -3
Case 3
[4-(7-5(2-3)+2color(red)(")")]+3
= [4-(7-5(-1)+2color(red)(")")]+3
= [4-(7+5+2color(red)(")")]+3
= [4-(14color(red)(")")]+3
= [-10]+3
= -7
Note Putting the missing right parenthesis outside the brackets would result in a meaningless expression.
