56X125用简便方法计算

56x125=125x(8x7)=(125x8)x7=1000x7=7000

56*125=125*8*7=1000*7=7000

88x125=11x8x125=(125x8)x11=1000x11=11000 祝学习进步,望采纳~~

56x125=7*8*125=7*1000=7000

56x125=7x8x125=7x1000=7000如有帮助请采纳,手机请点击右上角的满意,谢谢!!

56*125=7*(8*125)=7*1000=7000

=56x(100 25)=5600 1400=7000

50*125=6250;6*125=750:;625+750=7000

56X125X9=(8*125)*(7*9)=1000*63=63000

56*125*9 36*111+188*8=7*8*125*9 =36*(100+11)+(100+8*11)*8=7*1000*9 =3600+36*11+800+8*8*11=63*1000 =4400+11*(36+8*8)=63000 =4400+11*(36+64) =4400+11*100 =4400+1100 =5500
