Question

ME AJUDEMM! calcule a multiplicação:

a) (-2)×(-4)×(+5)×(-2) =

b) (+2)×(+2)×(+5)×(+3)=

c) (-20)×(-1)×(+2)×(+1)=

d) (-11)×(-2)×(-3)×(+1)=​

Answer 1

a) (-2)×(-4)×(+5)×(-2) =

(8) . (-10) = -80

b) (+2)×(+2)×(+5)×(+3)=

(4) . (15) = 60

c) (-20)×(-1)×(+2)×(+1)=

(20) . (2) = 40

d) (-11)×(-2)×(-3)×(+1)=

(22) . (-3) = -66

Bons estudos! :-)
