Answer 1

Resposta:

A) 1

B) 3

C) -5

D) 5

E) 2

F) 34

G) -21

H) 80

I) 260

J) 40

K) -40

Explicação passo-a-passo:

A) + (+1) = +1

B) + (+3) = +3

C) - (+5) = -5

D) + (+5) = +5

E) 8 + (-6) = 8 - 6 = +2

F) 25 - (-9) = 25 + 9 = +34

G) -20 - (+1) = -20 - 1= -21

H) 100 - (+20) = 100 - 20 = +80

I) 200 + (+60) = 200 + 60 = +260

J) 40 - (-20) - (+20) = 40 + 20 - 20 = +40

K) 25 + (-35) + (-30) = 25 - 35 - 30 = -40
