125×56脱式计算- 125×56 =125*8*7 =1000*7 =7000

125x56 =125×8×7 =1000×7 =7000

125x64 =125x8x8 =1000x8 =8000

125×23+431 =125×(20+3)+431 =2500+375+431 =2500+375+425+6 =2500+800+6 =3300+6 =3306 感觉直接计算更简便些

125×39×2×8=125×8×39×2=1000×78=78000

=5×1000÷125 =5×(1000÷125) =5×8 =40

325138+125=325263

125×46 =125×(40+6) =125×40+125×6 =5000+750 =5750

16×125简便脱式运算 解: 16×125 =2×(8×125) =2×1000 =2000

125*8*11*5 =1000*55 =55000
