42.5*99+42.5*2-42.5怎样简便计算
42.5*99+42.5*2-42.5怎样简便计算
42.5*99+42.5*2-42.5怎样简便计算
42.5*99+42.5*2-42.5
=42.5*(99+2-1)
=42.5*100
=4250
42.5*99+42.5*2-42.5
=42.5*(99+2-1)
=42.5*100
=4250
42.5*99+42.5*2-42.5
=42.5*(99+2-1)
=42.5*100
=4250
42.5*99+42.5*2-42.5=42.5*(99+2-1)=42.5*100=4250
42.5*99+42.5*2-42.5
=42.5*(99+2-1)
=42.5*100
=4250
=42.5*(99+2-1)
=42.5*100
=4250
=42.5X(99+2-1)
=42.5X100
=4250
一定对
