四年级简便计算题

300÷125÷8=300÷(125×8)=300÷1000=0.3 396-96-172-28 =(396-96)-(172+28)= 300-200 = 100 125*24 = 125*8*3 = 1000*3 = 3000 26*15 = (20+6)*15 = 20*15 + 6*15 = 300+90 =390 25*99*4 = 25*4*99 = 100*99 = 9900 250*32 = 250*4*8 = 1000*8 = 8000 (98+98+98+98)*25 = 4*98*25 = 4*25*98 = 100*98 = 9800 472*5*20 = 472*(5
