Hola espero que te ayude

Explicación paso a paso:

A) (2-10)+ [5-(8+2)]

=(-8)+[5-10]

=(-8)+(-5)

=-13

b) (12-3)-[1- (2-6)]

=9-[1-(-4)

=9-5

=4

c) 9-(+5)+ [7 +(-10)]

=9-(+5)+(-3)

=4+(-3)

=1

d) 10-(-2)- [5-(+12)]

=10-(-2)-(-7)

=12-(-7)

=19

e) 8-(6+4)- (5-7)

=8-10-(-2)

=(-2)-(-2)

=0

f) 1+ (6-9] - (8-12)​

=1+(-3)-(-4)

=-2-(-4)
