This kata should not be tagged as OOP.

Your preloaded code in the terminal does not declare the variables 'a' and 'b' when the method is defined.

Done

Fixed

Not an issue

Question is confusing. It says to create a count for each number 1-1000 that can be divided by the numbers 1-25, not say how many times 1000 can be divided by the numbers 1-25, which is what provides the final answer!

I like how this kata can be solved by just returning the result, instead of computing it.
Every now & then similar situation happen in real code: You need to return something that is expensive to compute but doesn't change. In that case it's often worth pre-computing the result instead of re-computing it over and over — especially if the value is needed very often.

However, mind you that returning (for example) a constant may not be particularly intention revealing (e.g. in this case).

You probably just need to replace puts h with h. The return value of puts is nil.
