− 2 · (−8) =
(−21): (−7)=
(−3) · (+1) =
- 15: (+3)=
[(−2) · (−10)]: (+5)=

Answer 1

Explicación paso a paso:

(-2) . (+3) = -6

-2 . (-8) = +16

(-21) : (-7) = +3

(-3) . (+1) = -3

-15 : (+3) = -5

[(-2) . (-10)] : (+5) = +20 : (+5) = +4

Answer 2

Explicación paso a paso:

(-2).(+3)= -6

-2.(-8)=16

(-21):(-7)=3

(-3).(+1)= -3

-15:(+3)= -5

[(-2).(-10)]:(+5)=[+20]:(+5)=+20:+5=+4
