2² - 3 x [-2² + 4 x (7 - (1 - 3))] + 12 ÷ 4 =
4 - 3 x [4 + 4 x (7 - (-2))] + 3 =
4 - 3 x [4 + 4 x (7 + 2)] + 3 =
4 - 3 x [4 + 4 x 9] + 3 =
4 - 3 x [4 + 36] + 3 =
4 - 3 x 40 + 3 =
4 - 120 + 3 = - 113
Ou
[2² - 3 x [-2² + 4 x (7 - (1 - 3))] + 12] ÷ 4 =
[4 - 3 x [4 + 4 x (7 - (-2))] + 12] ÷ 4 =
[4 - 3 x [4 + 4 x (7 + 2)] + 12] ÷ 4 =
[4 - 3 x [4 + 4 x 9] + 12] ÷ 4 =
[4 - 3 x [4 + 36] + 12] ÷ 4 =
[4 - 3 x 40 + 12] ÷ 4 =
[4 - 120 + 12] ÷ 4 =
- 104 ÷ 4 = - 26

2^2-3[-2^2+4(7-(1-3))]+12/4
4-3[4+4(7-(-2))]+3
1[4+4(9)]+3
4+36+3 = 43

2² - 3 [-2² + 4 (7 - (1 - 3))] + 12 / 4
4 - 3 [-4 +4 (7- (-2))] + 3
Obs: Acho que está faltando um sinal entre a parte +4 e (7-..., não está?
