125×56脱式计算%

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

125×56脱式计算 =125x8x7 =1000x7 =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

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

125x30x24 =125x30x(8*3) =125*8*3*30 =1000*90 =90000

125x25x8x8=(125x8)x(25x8)=1200 [49十(31X56)]除以7 =49÷7+31X56÷7 =7+31X8 =7+248 =255

1. 4×102-2×49 =408-2×49 =408-98 =310 2. 25×(2+4) =25×2+25×4 =50+100 =150 3. 12×5+8 =60+8 =68 4. 99×101 =99×(100+1) =99×100+99×1 =9900+99 =9999 5. 25×(78×4) =25×4×78 =100×78 =7800 6. (25+12)×4 =25×4+12×4 =100+48 =148 7. ...

(1)56×(200-155)=56×45=2520;(2)480×15+208=7200+208=7408;(3)25×4×47 =100×47=4700;(4)125×8×5=1000×5=5000;(5)48×25=12×(4×25)=12×100=1200;(6)34×99+34=34×(99+1)=34×100=3400.
