(4-6)(5-6) -(8-4).(8 - 7) =

=−2(5−6)−(8−4)(8−7)

=(−2)(−1)−(8−4)(8−7)

=2−(8−4)(8−7)

=2−4(8−7)

=2−(4)(1)

=2−4

=−2 → Respuesta.

(-4).[(-3).(5 - 8)-6.(-9+4)]+14 =

=−4((−3)(−3)−6(−9+4))+14

=−4(9−6(−9+4))+14

=−4(9−(6)(−5))+14

=−4(9−(−30))+14

=(−4)(39)+14

=−156+14

=−142 → Respuesta.

(10 -14):(-4)+(22 - 30):(+4) + 6 =

=−4−4+22−30/4+6

=1+22−30/4+6

=1+−8/4+6

=1+−2+6

=−1+6

=5 → Respuesta.
