Question

f) 18-(-5-2-3)=
g) 20 - (- 6 + 8)-(-1 + 3 )=
h) - 32 -1 -(- 12 + 14 )=
i) 7 + (-5-6)-(-9 + 3 )=

Answer 1

Oiê, td bom?

$18 - ( - 5 - 2 - 3) \\ 18 - ( - 10) = 18 + 10 = 28$

$20 - ( - 6 + 8) - ( - 1 + 3) \\ 20 - 2 - 2 = 16$

$- 32 - 1 - ( - 12 + 14) \\ - 33 - 2 = - 35$

$7 + ( - 5 - 6) - ( - 9 + 3) \\ 7 - 11 + 6 = 2$

Bons estudos!
