Answer 1

Explicação passo-a-passo:

4°) Calcule:

a) + 3+ 5+ 2 + 1 =

8+2+1=

10+1=

11

b) – 9 – 2 – 10 =

-11-10=

-21

c) + 20 – 21 =-1

d) + 40 – 11 =29

e) + 100 – 100 =0

f) + 5 + ( 7 – 3) =

+5+(4)=

9

g) – 6 – (– 3 + 2) =

-6-(-1)=

-5

h) 6 – 8 – 3 – 7 + 2 + 10 – 6 =

-2-(-4)+12-6=

2+6=

8

i) 3 – { – 6 – [10 – 2 + (– 7 + 10)]} =

3-{-6-[10-2+(3)]}=

3-{-6-[10-5]}=

3-{-6-[5]}=

3-{-11}=

14
