-6 : ( -1 + 2 - 3)
200: [ - ( -9 : 3 -2 ) ] =
[ 20 : ( -4) +10 - 4 . 2 ] : (-3) +7 : 2 =
(-2 -5 ) + [ -1 + 10 : ( -4 + 2 ) ] =

Answer 1

Resposta:

1) -49

2) +3

3) +40

4) +4,5

5) - 13

Explicação passo-a-passo:

1) -40-3.2-12/4 = -40-6-3 = -49

2) -6/ (-2) = -6/-2 = +3

3) 200/[-(-3-2)] = 200/(+5) = 40

4) [20/-4+10-4.2]/-3+7/2 = [-5+10-8] = -3/-3+7/2 = +1+3,5 = 4,5

5) -7 + [-1+10/-2] = -7 + [-1-5] = -7-6 = -13
