谢谢你们,快点

Answer 1

NO.1:(1 + 2) / 3 + 4 + 5 = 10
NO.2:(1 + 2) * 3 - 4 + 5 = 10
NO.3: 1 - (2 - 3) * 4 + 5 = 10
NO.4: 1 - (2 - 3) * (4 + 5) = 10
NO.5:(1 + 2) * 3 - (4 - 5) = 10
N0.6: 1 + 2 + 3 * 4 - 5 = 10
N0.7:12 - 3 - 4 + 5 = 10

Answer 2

(1+2+3-4)*5=10
还有很多，没细算～

Answer 3

(1+2+3-4)*5=10
1*2*(4-3)*5=10
