multiplique os inteiros
A)(+8)×(+3)
B)(+7)×(-8)
C)(-6)(-9)
D)(+3)(-7)(-11)
E)×(-8)
F)(-2)(+5)
G)(+1)(-4)(+5)
H)(-5)×(-14)
I)(-5)×0
J)(-7)(-8)(-2)

Answer 1

Olá,

Vamos lá,

A)(+8)×(+3) = 8 x 3 = 24
B)(+7)×(-8) = 7 x -8 = -56
C)(-6)(-9) = -6 x -9 = 54
D)(+3)(-7)(-11) = 3 x - 7 x - 11 = - 21 x - 11= 231
E)×(-8) = - 8
F)(-2)(+5) = -10
G)(+1)(-4)(+5) = - 4 x 5 = -20
H)(-5)×(-14) = 70
I)(-5)×0 = 0
J)(-7)(-8)(-2) = 56 x -2 = -112

Answer 2

A)
= (+8)×(+3) = + 24

B)(+7)×(-8) = - 56

C)(-6)(-9) = + 54

D)(+3)(-7)(-11) = 3.77 = + 231

E) 1×(-8) = - 8

F)(-2)(+5) = -10

G)(+1)(-4)(+5) = - 4.(5) = - 20

H)(-5)×(-14) = + 70

I)(-5)×0 = 0

J)(-7)(-8)(-2) = 56.(-2) = - 112
