Answer 1

A) (+3)+(-2)+(-5)

= +3 -2 -5

= +3 -7

= -4

b) (-2)-(+1)-(+5)

= -2 -1 -5

= -8

c) (+4)+(-2)-(+3)

= +4 -2 -3

= +4 -5

= -1

d) (+5)-(-3)-(-1)

= +5 +3 +1

= +9

e) (+4)+(-6)-(+7)-(-6)+(+7)

= +4 -6 -7 +6 +7

= +4 -13 +13

= +4

f) (-3)-(-5)+(-6)+(+8)-(-4)

= -3 +5 -6 +8 +4

= -9 +17

= +8

g) +(-3+8)-(-3+8)+(5-6)

= -3 +8 +3 -8 +5 -6

= -17 +16

= -1

h) -(-3-1)-(-6+4-1)-6-(-3+2)

= +3 +1 +6 -4 +1 -6 +3 -2

= +14 -12

= +2

I) 18-(-5-2-3+20-(-6+8)-(-1-8+3)

= +18 +5 +2 +3 -20 +6 -8 +1 +8 -3

= +42 -31

= +11

J) -32-1(-12+14+7)+(-5-6-9+3)-17

= -32 -1 -12 +14 +7 -5 -6 -9 +3 -17

= - 65 -17 +24

= -82 +24

= -58

Espero ter ajudado!!!
