41.2*8.1+11*1.25+53.7*1.9 怎样巧算?
是最新的

41.2*8.1+11*1.25+53.7*1.9 怎样巧算?是最新的
=41.2*(10-8.1)+53.7*8.1+11*1.25
=53.7*8.1+41.2*10-41.2*8.1++11*1.25
=(53.7-41.2)*8.1+412+11*1.25
=12.5*8.1+1.1*1.25+412
=12.5*(8.1+1.1)+412
=12.5*9.2+412
=115+412
=527

41.2*8.1+11*1.25+53.7*1.9
=41.2*8.1+11*1.25+(41.2+12.5)*1.9
=41.2*8.1+41.2*1.9+11*1.25+12.5*1.9
=41.2*(8.1+1.9)+12.5*(1.1+1.9)
=41.2*10+12.5*3
=412+37.5
=449.5
