简便算法,6.8乘0.99+0.068
6.8*0.99+0.068
=6.8*(1-0.01)+0.068
=6.8*1-6.8*0.01+0.068
=6.8-0.068+0.068
=6.8
6.8*（0.99+0.01）
=6.8*1
=6.8
0.068*（99+1）=6.8
=6.8 x(1-0.01)+6.8 x 0.01
=6.8(1-0.01+0.01)
=6.8
6.8*0.99+6.8*0.01=（0.99+0.01）*6.8=6.8
6.8×（1-0.01）+0.068
=6.8-6.8×0.01+0.068
=6.8-0.068+0.068
=6.8
6.8乘0.99+6.8乘0.01等于6.8乘1
