4.82*0.59+0.41*1.59-0.323*5.
4.82×0.59+0.41×1.59-0.323×5.9
=4.82×0.59+0.41×(1+0.59)-0.323×10×0.59
=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
=0.59+0.41+0.59

4.82*0.59+0.41*1.59-0.323*5.9
=4.82*0.59+0.41*(1+0.59)-0.323*(5.9*0.1)/0.1
=4.82*0.59+0.41+0.41*0.59-(0.323/0.1)*(5.9*0.1)
=4.82*0.59+0.41+0.41*0.59-3.23*0.59
=0.59*(4.82+0.41-3.23)+0.41
=0.59*2+0.41
=0.59+(0.59+0.41)
=0.59+1
