对不起，发错了，反正就是38.14-5.86-4.14 4.587+3.47-2.47 24.62-(4.63-1.85)这三题简便运算，递等式计算
38.14-5.86-4.14
=(38.14-4.14)-5.86
=34-5.86
=28.14
4.587+3.47-2.47
=4.587+(3.47-2.47)
=4.587+1
=5.587
24.62-(4.63-1.85)
=24.62-4.63+1.85
(这题是不是写错了，应该是24.63吧？如果不是那还真不知道怎么算简便了）
=(38.14-4.14)-5.86
=34-5.86
=28.14
4.587+3.47-2.47
=4.587+(3.47-2.47)
=4.587+1
=5.587
24.62-(4.63-1.85)
=24.62-4.63+1.85

38.14-5.86-4.14
= 38.14-（5.86+4.14）
= 38.14-10
= 28.14
4.587+3.47-2.47
= 4.587+（3.47-2.47）
= 4.587+1
= 5.587
24.62-(4.63-1.85) (这个参数是不是写错了？！ 我认为小数部分应该是一样的。)
= 24.62-4.63+1.85
= 19.99+1.85
= 21.84
= 38.14-（5.86+4.14）
= 38.14-10
= 28.14
4.587+3.47-2.47
= 4.587+（3.47-2.47）
= 4.587+1
= 5.587
24.62-(4.63-1.85) (这个参数是不是写错了？！ 我认为小数部分应该是一样的。)
= 24.62-4.63+1.85
= 19.99+1.85
= 21.84

24.62-(4.63-1.85)??
是不是写错了应该为24.62-(4.62-1.85)
=24.62-4.62+1.85
=20+1.85

38.14-4.14=34 34-5.86=28.14
3.47-2.47=1 4.587+1=5.587
24.62-4.63=19.99 19.99+0.01=20 20+1.85=21.85 21.85-0.01=21.84
没看懂楼主的意思，不知道这么做对不对
3.47-2.47=1 4.587+1=5.587
24.62-4.63=19.99 19.99+0.01=20 20+1.85=21.85 21.85-0.01=21.84

38.14-5.86-4.14=34-5.86=28.14
4.587+3.47-2.47=4.587+1+2.47-2.47=5.587
24.62-(4.63-1.85)=24.63-4.63+1.84=20+1.84=21.84
4.587+3.47-2.47=4.587+1+2.47-2.47=5.587
