(24 – 7 . 8) : 8 . (5 – 12) – 56 : (1 – 4.2) + 48 : (– 10 – 2) =

=16.2/8(5−12)−56/1−4.2+48−10−2

=2.025(5−12)−56/1−4.2+48−10−2

=(2.025)(−7)−56/1−4.2+48−10−2

=−14.175−56/1−4.2+48−10−2

=−14.175−56−3.2+48−10−2

=−14.175−(−17.5)+48−10−2

=3.325+48−10−2

=3.325+48−12

=3.325+−4

=−0.675 → Respuesta.

- 64 : ( -4 ) : ( -2 ) - (-42 + 70) : (7 - 11) - (12 - 4 . 9).(-2)=

=16−2−(−42+70/7−11)−(12−4.9)(−2)

=−8−(−42+70/7−11)−(12−4.9)(−2)

=−8−28/7−11−(12−4.9)(−2)

=−8−28−4−(12−4.9)(−2)

=−8−(−7)−(12−4.9)(−2)

=−1−(12−4.9)(−2)

=−1−(7.1)(−2)

=−1−(−14.2)

=13.2 → Respuesta
