50.33减33.4加8.67减16.66用简算怎么算？

Answer 1

楼主33.4少输入一个3，貌似是33.34，可以取整简算
50.33—33.34+8.67—16.66 移项
=50.33+8.67—33.34—16.66
=59—(33.34+16.66) 先计算减数取整
=59—50
=9

Answer 2

加法交换律
指两个加数相加，交换加数的位置，和不变。即a+b=b+a。
加法结合律:
是指三个数相加，先把前两个数相加，或者先把后两个数相加，和不变。
50.33－33.4+8.67－16.66
=(50.33+8.67)－(33.4+16.66)
=59－50.06
=8.94

Answer 3

50.33-33.4+8.67-16.66
=50.33+8.67-（33.4+16.66）
=59-50.06
=8.94

Answer 4

50.33-33.4+8.67-16.66
=50.33+8.67-33.4－16.66
=59-33.4-16.66
=8.94
