Number Game

Anonymous
Not applicable

Here's an interesting game:

 

Can we make all the numbers from 0 to 21 just by using 2, 3 and 5?

 

It is possible to do.

 

So for example;

0 = 5 - 3 - 2

10 = 5 + 3 + 2

Forgot to add - you must use all the 3 numbers in your solution.

And if you square a number, it DOES use your 2.

Just a few for starters - quiet at the moment and could easily get carried away.

4: (3+5) / 2
9: (5-2)*3
13: (5*3)-2
17: (5*3)+2
