44×55×66=?怎么巧算?
=(45*55-55)*66
=2420*(65+1)
=157300+2420
=159720

解: 44*55*66
=11*11*11*4*5*6
=1331*120
=159720

44*55*66
=(4*11)*(5*11)*(6*11)
=(4*5*6)*11*11*11
=(20*6)*1331
=120*1331
=159720

44×55×66
=4*5*6*11^3
=120*1331
=122100+26620
=159720

11*4*11*5*11*6
=1331*120
=26620

=11×11×4×5×6
=1331×120
=159720
