h) (-7) - [3 - (4 - 9) =. quién me puede ayudar por favor​

Answer 1

Explicación paso a paso:

a.

$6 + 5 + 7 + 2 = 20$

b.

$8 + (4 - 8) = 8 + ( - 4) = 8 - 4 = 4$

c.

$10 - 16 + 9 = 3$

d.

$15 - 2 - ( - 4) = 15 - 2 + 4 = 17$

e.

$15 - (10 - (12)) = 15 - (10 - 12) = 15 - ( - 2) = 15 + 2 = 17$

f.

$12 - 17 - ( - 8) = 12 - 17 + 8 = 3$

g.

$- 6 + (5 + ( -10)) = - 6 + ( - 5) = - 6 - 5 = - 11$

h.

$- 7 - (3 - ( - 5)) = - 7 - (3 + 5) = - 7 - 8 = - 15$
