36+99乘36用脱式计算怎样简便

36+99+36 =36*(99+1) =36*100 =3600 供参考

+36吧。 不然就是硬心算了。 129600-1296=128304 36×99+36=36×(99+1)=36×100=3600

36×99 =36×(100-1) =36×100-36×1 =3600-36 =3564

0.36乘99 =0.36×(100-1) =0.36×100-0.36 =36-0.36 =35.64

25×435+25-36×25 =25*(435+1-36) =25*400 =10000 199+99×99 =100+99+99*99 =100+99*(99+1) =100+9900 =10000 8000÷125 =8*1000÷125 =8*8 =64

77-46+3265-38+2679+19-5658-36+2784-27+16=4+27-1693+23+9469-(39-23)99+(25-24)77-76+3261-38+2679+19-1616+77-2618-36+2787-27+1630+(23-29)73-23-493-(39-23)71-(25-24)99-46+3265-39+2699+99-5656+94-2659-36+2994-29+9630-(23-29)93-2...
