You can put this solution on YOUR website!
Consider the numbers %283%5E0%29%283%5E1%29%283%5E2%29%283%5E3%29
OR 1,3,9,27
Using these numbers you can get all the numbers from 1-40
I'll leave it to you to find out
Here's a little to get you started
1-We have a 1pound weight
2- Put the 1Lb on 1 scale and the 3lb on the difference. The differencd is 2
3-We have a 3lb weight
4 - Put the 1 and 3 on the same scale
5- Put the 9 on 1 scale and the 1+3 on the other The difference is 5
Now its your turn!!
