5.(-4)+2.(-3)=

=−20+(2)(−3)

=−20+−6

=−26 → Respuesta.

20:(-5)-8:(+2) =

=−4−8/2

=−4−4

=−8 → Respuesta.

2.(-8)-3.(-7)-4.(+3)=

=−16−(3)(−7)−(4)(3)

=−16−(−21)−(4)(3)

=5−(4)(3)

=5−12

=−7 → Respuesta.

6:(+2)+5.(-3)-12:(-4)=

=3+(5)(−3)−12−4

=3+−15−12/−4

=−12−12/−4

=−12−(−3)

=−9 → Respuesta.
