=4400-2400
=2000
85*27+85*73
=85*(27+73)
=85*100
=8500
99*99+99
=99*99+99*1
=99*(99+1)
=99*100
=9900
125*31
=125*(30+1)
=125*30+125*1
=3750+125
=3875
998+1413+9989
=(987+11)+1413+9989
=(987+1413)+(11+9989)
=2400+10000
=12400
9/13+13/9+11/13+14/9+6/13
=(9+13+11+14+6)*(1/13)
=(9+11+14+6+13)*(1/13)
=(20+13)*(1/13)
=2又7/13
2003-2002+2001-2000+1999-1998+1997
=(2003+1997)-(2002+1998)+(2001+1999)-2000
=4000-4000+4000-2000
=2000
88+76+81+82+77+80+79+83
=(88+82)+(77+83)+(81+79+)+(76+80)
=170+160+160+156
=646
28/3*26*15/26/14
=(26/26)*(15/3)*28*14
=1960
60000/2/125/5/8
=60000/【(2*5)*(8*125)】
=60000/10000
=6
打得很辛苦啊喂
