H) −(−3 − 1) − (−6 + 4 − 1) − 6 − (−3 + 2) =
I) 18 − (−5 − 2 − 3) + 20 − (−6 + 8) − (−1 – 8)=
J) −32 − 1 − (−12 + 14 + 7) + (−5 − 6 − 9 + 3 )=

Answer 1

Resposta:a)(+3)+(-2)+(-5)= -4

b)(2)-(+1)-(+5)= -4

c)(+4)+(-2)-(+3)= -1

D) (+5)-(-3)- (-1) =9

E) (+4) + (- 6)- (+7)- (- 6) + (+7) =4

F) (-3)-(-5) + (-6) + (+8)-(-4) =8

G) + (- 3 + 8)-(-3 + 8) + (5-6) = -1

H)-(-3-1) - (-6+4 -1)-6-(-3 + 2) =2

I) 18-(-5--2-3) + 20 - (-6+8) - (-1-8 + 3) =48

J) -32-1-(-12+14+ 7) + (-5-6-9+3) - 17 = -76
