h) (6 - 12 + 2) - (11- 4 + 2) =​

Answer 1

Explicación:

c)10 + (-3 + 5)

=10+(+2)

=10+2

=12

d)12 – (8 – 11)

=12-(-3)

=12+3

=15

e)(3 + 8) – (2 + 6)

=11-8

=3

f)(15 - 9) - (10 - 7)

=6-3

=3

g)12 - (7 + 11 - 14 - 8)

=12-(-4)

=12+4

=16

h) (6 - 12 + 2) - (11- 4 + 2)

=-4-(9)

=-4-9

=-13
