The neat part is that if you add the numbers together and they're still too large to tell, you can do it again. In your example, you get 15. If you do it again, you get 6, which isn't the best example because 15 is pretty obvious, but it works.
But how do I prove it for 6
Get 6 apples. Duh.
There is a mathematical proof that 1 + 1 = 2 so surely you could make a proof for 6 รท 3 = 2

Prove it for 2, then un-distribute.
