简算,9999×0.66+3333×0.02
简算,
9999×0.66+3333×0.02

简算,9999×0.66+3333×0.02
9999×0.66+3333×0.02
=3333×1.98+3333×0.02
=3333×(1.98+0.02)
=3333×2
=6666

6797.9868

可以化成为:3333X3X0.66+3333X0.02=3333X(3X0.66+0.02)=3333X2=6666

有那么多时间考虑解法还不如计算器拿出来按按,省时方便

9999×0.66+3333×0.02
=3333×1.98+3333×0.02
=3333×(1.98+0.02)
=3333×2
=6666
