Answer 1

Respuesta:

$+ 8 - ( + 8) = 8 - 8 = 0$

$- 7 - ( - 2) = - 7 + 2 = - 5$

$- 9 - ( - 7) = - 9 + 7 = - 2$

$+ 3 - ( + 9) = 3 - 9 = - 6$

$+ 2 - ( + 2) = 2 - 2 = 0$

$- 9 - ( - 5) = - 9 + 5 = - 4$

$+ 6 - ( + 10) = 6 - 10 = - 4$

$- 4 - ( - 11) = - 4 + 11 = 7$

$- 8 - ( + 6) = - 8 - 6 = - 14$

$9 - ( + 2) = 9 - 2 = 7$

$- 12 - ( + 8) = - 12 - 8 = - 20$

$- 6 - 0 = - 6$

$- 3 - ( + 8) = - 3 - 8 = - 11$

$- 20 - ( + 12) = - 20 - 12 = - 32$

$- 8 - ( + 4) = - 8 - 4 = - 12$

$12 - ( - 20) = 12 + 20 = 32$
