用拆分+组合的方法,口算就能算出结果!
11X12+2400X0.12+1.2X150
=(10+1)X12+24X100X0.12+1.2X15X10
=120+12+24X12+12X15
=120+12+12(24+15)
=120+12+12X39
=120+12+12(40-1)
=120+12+12X40-12
=120+480
=600
11X12+2400X0.12+1.2X150
=(10+1)X12+24X100X0.12+1.2X15X10
=120+12+24X12+12X15
=120+12+12(24+15)
=120+12+12X39
=120+12+12(40-1)
=120+12+12X40-12
=120+480
=600
