34.83*0.59+0.41*1.59-0.324*5.9
=3.483*0.59+0.41*(1+0.59)-3.24*0.59
=(3.483-3.24+0.41)*0.59+0.41
=0.38527+0.41
=0.79527
再问: 等于19.92,你算错了吧?是34.83
再答: 嗯
再问: 那到底过程是什么,要简便的,我就是想不出简便的过程才来问的啊
再答: =3.483*0.59+0.41*(1+0.59)-3.24*0.59 =(3.483-3.24+0.041)*5.9+0.41 =3.2*5.9+0.41 =18.88+0.41 =19.29 感觉这是最简便的了
=(3.483-3.24+0.41)*0.59+0.41
=0.38527+0.41
=0.79527
再问: 等于19.92,你算错了吧?是34.83
