Yep, I first tried to find a solution for every number from 0 to 50 using 4 twos, but it was not fun. So I changed the number of twos, played with the buttons available on the calculator, and finally picked the "puzzles" (the numbers) that I found the most interesting. As you see, many of them aren't even integers in the final game. I found it fun to wander on the side of negatives, fractions, powers and square roots too!
