计算：4.82×0.59+0.41×1.59-0.323×5.9=．

Question

计算：4.82×0.59+0.41×1.59-0.323×5.9= ____ ．

Answer 1

分析：将4.82×0.59+0.41×1.59-0.323×5.9变形为4.82×0.59-3.23×0.59+0.41×1.59，再两次运用乘法分配律简便计算．4.82×0.59+0.41×1.59-0.323×5.9，=4.82×0.59-3.23×0.59+0.41×1.59，=（4.82-3.23）×0.59+0.41×1.59，=1.59×0.59+0.41×1.59，=1.59×（0.59+0.41），=1.59×1，=1.59．故答案为：1.59．点评：考查了四则混合运算中的巧算，注意灵活运用积不变规律，运算律简便计算．
