8.9X9.9+11X0.99;3.46X1.23+3.46X4.56+5.79X6.54的简便计算
8.9X9.9+11X0.99;3.46X1.23+3.46X4.56+5.79X6.54的简便计算
8.9X9.9+11X0.99;3.46X1.23+3.46X4.56+5.79X6.54的简便计算
8.9X9.9+11X0.99
=89X0.99+11X0.99
=0.99X(89+11)
=0.99X100
=99
3.46X1.23+3.46X4.56+5.79X6.54
=3.46X(1.23+4.56)+5.79X6.54
=3.46X5.79+5.79X6.54
=5.799X(3.46+6.54)
=5.79X10
=57.9
8.9X9.9+11X0.99
=89X0.99+11X0.99
=0.99X(89+11)
=0.99X100
=99
3.46X1.23+3.46X4.56+5.79X6.54
=3.46X(1.23+4.56)+5.79X6.54
=3.46X5.79+5.79X6.54
=5.799X(3.46+6.54)
=5.79X10
=57.9
