Answer 1

20. Resolva:
A) (+3)+(-2) + (-5)
= 3-2-5
= 1 - 5
= - 4

B) (2)+ (+1)-(+5) =

2+1-5 = 3-5 = - 2

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

D) (+5)-(-3)-(-1)
= 5+3+1
= 8+1
= 9

D) (+4)+(-6) +(+7)-(-6) + (+7)
= 4-6+7+6+7
= - 2+ 20
= 18


F) (-3)-(-5) + (-6) + (48)-(-4)
= - 3 + 5 - 6 + 48 + 4
= 2 + 42 + 4
= 44 + 4
= 48
