I was bored and decided to make a calculator in phun..
But this isn`t a normal one, check it out to see what`s special

Controlls
Use the numbers on the top of your keyboard to get a number.
Reduce lag
Press L to reduce lag (This will delete some balls)
How does it work?
Press P

Enjoy and rate it

There is only 1 problem:
The 5 doesn`t work proper, when you press 5 the "machine" will break..
Who can solve this?
