Question

01. Efetue:

a) (+6) – ( - 4) = b) (+8) – ( +4) =

c) (+10) – ( +3) = d) (- 8) – ( +6)

e) (-17) – ( -3) = f) (- 9) – ( -10) =

g) (- 8) – ( +12) = h) (+15) – (- 5) =​

Answer 1

Resposta:

A) (+6) – ( -3) = 6+3=9

B) (+4) – ( -9) = 4+9=13

C) (+10) – ( +3) = 10-3=7

D) (+8) – ( +9) = 8-9=-1

E) (-17) – ( -3) = -17+3= -14

F)(-9) – ( +10) = -9-10= -19

G) (-8) – ( -12) = -8+12=4

H) 15+(+5) = 15+5=20

I) 0 – = 10 = 0 -(-10)= 10

J) (-5) + (-8)= -5-8= -13

K) (-15)+( -8)= -15-8= -23

L)(-20)+(-7)= -20-7= -27

M) (-10)+(+12)= -10+12=2

N) 0 - 4 = -4

Acredito que seja assim:)
