Answer 1

A)5+(-8) = -3

B)(-2)-(-3) = (-2)+3 = 1

C)(-3)-(-9) = (-3)+9 = 6

D)(-7)-(-8) = (-7)+8 = 1

E)(-8)+(-6)-(-7) = (-8)-6+7 = (-14)+7 = (-7)

F)(-4)+(-6)+(-3) = (-4)-6-3 = (-13)

G)15-3(-1) = 15-4 = 11

H)32-(+1)-(-5) = 32-1+5 = 36

I)8-(+4-1) = 8-4+1 = 5

J)-5-(2+3-1) = (-5)-2-3+1 = (-10)+1 = (-9)

K)18+(-1+8+2) = 18-1+8+2 = 27

L)20-(+6-1+7) = 20-6+1-7 = 21-13 = 8

M)14+(+7)+(-6+4) = 14+7-6+4 = 21-2 = 19

N)15(2-4)-6 = 30-60-6 = -30-6 = -36

O)5+(6-8)+4 = 5+(-2)+4 = 5-2+4 = 6

P)6-3-1-2 = 6-6 = 0

Q)-(2-5)-3+8-1 = -2+5-3+8-1 = 13-6 = 7

R)-(10+1)-3+5-2 = -11-3+5-2 = -16+5 = -11

Espero ter ajudado ;3
