i need help with, what i believe is complicated but probably isnt, on this following problem. i need to write a sequence of instructions that will do:
variable5= -((variable1 + variable2) - variable3) + (variable2 - variable 4).
thank you in advance.

.data
V1 dd 24
V2 dd 37
V3 dd 123
V4 dd 18
V5 dd -1
-(( 24 + 37 ) - 123) + ( 37 - 18 )
( 61 - 123) + 19
-(-62) + 19
62 + 19 = 81
.code
Start: mov eax, V2 ; EAX = 37
push eax ; Save temporarily
sub eax, V4 ; 37 - 18 = 19
mov ecx, eax ; ECX = 19
pop eax ; EAX = 37 again
add eax, V1 ; EAX = 61
sub eax, V3 ; EAX = -62
neg eax ; EAX = 62
add eax, ecx ; Resolve parethesis
mov V5, eax ; V5 = 81
ret
