Thing is, when you are talking Math you are usually assuming base 10.
But for the database, 2 is a symbol. You sure can have a typeless
For example, in your line of reasoning the database wouldn't know if that 2 is a number or a string. That is not so bad, as automatic type casting in this case would be pretty much straightforward. But what about 1011? You surely want to know if that's decimal, octal, hexadecimal or binary, don't you?
