All odd numbers are divisible by 2.
You just get a decimal in the quotient.
That’s not what divisible means
It is, just not in mathematics.
what non-mathematical meaning are we talking about here?
I think what they mean is still a mathematical meaning, just a separate definition of ‘divisible’ not limited to integers. The term is usually used for the set of integers, but really you could define it on any set.
“For x,y in S, x is called divisible by y if and only if x/y lies in S.” could be such a definition. Obviously you also need a definition of “/”, which is usually x/y=a <=> a*y=x with any operation *. This usually involves an algebraic Ring.
(±sqrt(81) + 3)/6 is both odd and divisible by 2
If youre gonna define divisibility on a non-mathematical term you could simply define it on the Ring of real numbers instead.
- Try again.
That’s odd…
that’s even
I can’t even…
