Answer 1

500:25=20
14•5=70
20•70=1,400

40•50=2,000
25•2=50
2,000•50=100,000
100,000•9=900,000

25•125=3,125
4•8=32
3,125•32=100,000

16•5=64
5•5=25

250:5=50
12:3=4
4•4=16
50•4=200
200•4=800

14-11=3
22+3=25
86+25=111

Answer 2

500:25145 = 500/25 * 14 * 5 = 20 * 14 * 5 = 1400

40509225 = 40 * 50 * 9 * 2 * 25 = 900,000

251254*8 = 25 * 125 * 4 * 8 = 125,000

1645*5 = 16 * 4 * 5 * 5 = 1600

250:512:34 = (250/5) * (12/3) * 4 = 50 * 4 * 4 = 800

86+22+14-11 = 111
