Answer 1

Hola!

Resolvemos:

-4+2-(+2)-3

−4+2−2−3

=−2−2−3

=−4−3

=−7

5-(11-4(11-7)

5−(11−4(11−7))

=5−(11−(4)(4))

=5−(11−16)

=5−(−5)

=10

(-4)[12+3×(5-8)]

−4(12+3(5−8))

=−4(12+(3)(−3))

=−4(12+−9)

=(−4)(3)

=−12

6[18+(-4)(9-4)]-13

6(18−4(9−4))−13

=6(18+(−4)(5))−13

=6(18+−20)−13

=(6)(−2)−13

=−12−13

=−25

24-(-3)×[13-4-(10-5)]

=24−−3(9−(10−5))

=24−−3(9−5)

=24−(−3)(4)

=24−(−12)

=36
