4)]-18)-27+5 =

C) -27-{-19+(-15-(-27+5)-19]+28 - 39+2) -97 =​​​​

Answer 1

A) -(-3+5-6-7 +(2-8)-4+3]-6}-(-2)+3 =

{[-(3+(6)-1]-6}-(-2+3)=

{[-(3+6-1)]-6}-1=

{[-8]-6}-1=

-8-6-1= -15

B) -105-{-[15+ (3 -  4)]-18)-27+5 =

-105-{-[15 + 1]-18 - 27 + 5 =

-105-{-[15 + 1] -40 =

-105-{-16} -40 =

-105 - 16 - 40 =  -49

C) -27-{-19+(-15-(-27+5)-19]+28 - 39+2) -97 =

-27-{-19+(-15-(-22)-19]+13) -97 =

-27-{-19+(-12 + 13) -97 =

-27-{-19 + 1 - 97 =

-27- (-115) = 88
