6年级100道简便计算带答案带过程

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
