Flying Math Toys

You can slice down numbers in half. 
You can freeze numbers by clicking on them.
You can hold numbers and throw them, but it's tricky because of bugs - just hold the click and go under a number. (It should be different) 

Features I want to add:
Physics.
Throwing number at others combines them together - addition.
Figure out fun way to subtract, multiply, divide etc 
X equations, roots etc
