最佳解答:

1/2 - [ 3- (-1/3 + 1/4)] = 1/2- [ 3- (-1/12)] = 1/2- 37/12 6-37 = -------------- 12 -31 = ------ 12 7 = -2 ------ 12

其他解答:

1/2 - [ 3- (-1/3 + 1/4)] =1/2-(3+1/3-1/4) =1/2-3-1/3+1/4 =6/12-36/12-4/12+3/12 = -31/12 就是這樣|||||1/2 - [ 3- (-1/3 + 1/4)] = -31/12|||||1/2 - [ 3- (-1/3 + 1/4)] =1/2-(3+1/3-1/4) =1/2-3-1/3+1/4 =6/12-36/12-4/12+3/12 = -31/12 (ans)|||||1/2 - [ 3- (-1/3 + 1/4)] =1/2-(3+1/3-1/4) =1/2-3-1/3+1/4 =6/12-36/12-4/12+3/12 = -31/12
