41.2*8.1+11*9.25+53.7*1.9=?简算
41.2*8.1+11*9.25+53.7*1.9=?简算
41.2*8.1+11*9.25+53.7*1.9=?简算
41.2*8.1+11*9.25+53.7*1.9
=41.2*8.1+11*9.25+(41.2+12.5)*1.9
=41.2*8.1+41.2*1.9+12.5*1.9+11*(1.25+8)
=41.2*(8.1+1.9)+12.5*1.9+1.1*12.5+88
=41.2*10+12.5*3+88
=412+88+37.5
=500+37.5
=537.5
(41.2*8 + 41.2*0.1) + (9.25*10 + 9.25) + (53.7*2-53.7*0.1)
