812x4-1625 36*99+36
=(1+99)*36
11/【(7/8-5/12)*18】
=11/【7/8*18-5/12*18】
115*8/15-85/15/8
=115*8/15-85*8/15
=(115-85)8/15
20-4.8*2.5
=20-(4*2.5+0.8*2.5)
15.39-(5.39-2.7)
=15.39-5.39+2.7
6/13-3/8+7/3-5/8
=(6/13-7/13)-(3/8+5/8)
920/40+23*99
=23+23*99
=23*100
4.8/2.5/0.4
=4.8/(2.5*0.4)

=3248-1625
=1423
112*2+1
=224+1
=225

2/3*24*1/17
=16/17

5/36*72
=10

23243*2+8765
=55251

432*7+432*13
=8640

112+1/1+112
=224

125*4*25*8
=100000

1500*(1-40%)
=900

30/(1-25%-25%)
=60

1440/(1-20%)
=1800
