2014 Mathematics Game

2014 Mathematics Game is here!
Read the complete rules at Let's Play Math.

Essentially, you're supposed to use each of the digits 2, 0, 1, and 4 and mathematical operations to form the counting numbers from 1 to 100. It's yearly challenge that is fun for all ages!

I'll get you started with a few easy ones:

1 × (4 − 2) + 0 = 2

20 - 14 = 19

41 + 20 = 61

You can also use square root, factorial, decimals, and some other things.

If you can't quite make it to 100... try do all the couting numbers from 1 to 20 or some other smaller goal. (I was able to do them from 1 to 20 in a fairly short time so that much is definitely possible. We'll have to see if complete solutions exist.

This game is also 'live' at Math Forum where you can submit a complete solution, and possibly get it published.
