comment Is the statement “1/3 of the natural numbers are divisible by 3” true? Is anything similar to it true?
This formal statement is exactly the definition of natuarl density or asymptotic density.

These sound like high school students, right?

comment show if function is even or odd
You can always graph the function and see that it's definitely not even, that it in fact looks like it's odd (something others have proved below).

comment Is it wrong to tell children that 1/0 = NaN is incorrect, and should be ∞?
I suspect part of the confusion may be because of what IEEE 754 floating point numbers do when you divide by zero: 1/0 is postive infinity, (-1)/0 is negative infinity, and 0/0 is NaN.

comment Computing a very large number
bc can also compute it quickly. By the way, the secret of these languages (as opposed to C, and Java) is that they use numeric types that allow you to express arbitrary large integers by default (or, in the case of Ruby, they switch to those types transparently): (10**10).class => Fixnum, and (65534**65534).class => Bignum.

comment Why can ALL quadratic equations be solved by the quadratic formula?
@KCd: He might not know enough about math to understand complex numbers, in which case he can't always use the quadratic formula.
