0.41*1.59-8.43*0.59+4.42*0.59簡便方法

原式=0.41x（1+0.59）-0.59x8.43+4.42x0.59
=0.59x（4.42+0.41-8.43）+0.41
=0.59x3.6+0.41
=3.6x（1-0.41）+0.41
=3.6-2.6x0.41
=2.534

4.83×0.59+0.41×1.59-0.324×5.9=______.

4.83×0.59+0.41×1.59-0.324×5.9=4.83×0.59+0.41×（1+0.59）-3.24×0.5.9=4.83×0.59+0.41×1+0.41×0.59-3.24×0.59=（4.83+0.41-3.24）×0.59+0.41=2×0.59+0.41=1.18+0.4=1.58；故答案為：1.58.
