1.The numbers could be multiplyed by 2 to get to the soulution.
1=28
2=12
3=56
4=108
2. __2 x __27 __31 __111

I started to try and work out the first one and found out 13 and 11 equals 143 so I tried 13 first then tried 11. Finally 11 worked.
You have to be systematic to work it out because for the 1,I counted all the way from 3 t0 13 tring diffrent numbers.
