解答
(4+2/3) + 3/8 + (-5/6) + (-5/8) + (3+3/4)
  = 4 + 3 + [3/8 + (-5/8)] + [2/3 + (-5/6)]
  = ……大哥,你这是什么写到这一步了,相信你能接着算出来,难道不行吗?我不会啊,所以我才问吗,我要的是全部回答一位不会得理直气壮的小朋友的问题:(4+2/3) + 3/8 + (-5/6) + (-5/8) + (3+3/4)  = 4 + 3 + [3/8 + (-5/8)] + [2/3 + (-5/6)]  = 7 + (-2/8) + (-3/6)  = 7 + (-1/4) + (-1/2)  = 7 - (1/4 + 1/2)  = 7 - 3/4  = 6 + 1/4  我无语了回答一位不会得理直气壮的小朋友的问题(刚看走眼了):   (4+2/3) + 3/8 + (-5/6) + (-5/8) + (3+3/4)  = 4 + 3 + [3/8 + (-5/8)] + [2/3 + (-5/6)]  = 7 + (-2/8) + (-1/6)  = 7 + (-1/4) + (-1/6)  = 7 - (1/4 + 1/6)  = 7 - 5/12  = 6 + 7/12对不起错了。 是 (﹣4+2/3) + 3/8 + (-5/6) + (-5/8) + (3+3/4)   (-4+2/3) + 3/8 + (-5/6) + (-5/8) + (3+3/4)  = -4 + 3 + [3/8 + (-5/8)] + [2/3 + (-5/6)]  = -1 + (-2/8) + (-1/6)  = -1 + (-1/4) + (-1/6)  = -1 - (1/4 + 1/6)  = -1 - 5/12  = -(1 + 5/12)
