Question

4.82×0.59+0.41×1.59－0.323×5.9 用简便方法

Answer 1

计算过程如下：

4.82×0.59+0.41×1.59-0.323×5.9 

=4.82×0.59+0.41+0.41×0.59-3.23×0.59

 =（4.82+0.41-3.23）×0.59+0.41 

=2×0.59+0.41 

=1.59

混合运算：

如果一级运算和二级运算，同时有，先算二级运算。如果一级，二级，三级运算（即乘方、开方和对数运算）同时有，先算三级运算再算其他两级。

如果有括号，要先算括号里的数（不管它是什么级的，都要先算）。在括号里面，也要先算三级，然后到二级、一级。

Answer 2

4.82×0.59+0.41×1.59－0.323×5.9
=4.82×0.59－3.23×0.59+0.41×0.59+0.41
=0.59*（4.82-3.23+0.41）+0.41
=0.59*（1.59+0.41）+0.41
=0.59*2+0.41
=0.59+0.59+0.41
=0.59+1
=1.59
