This would be a better use of your time:

You might try looking up the definition of an algebraic number.

Heh, like I haven't already done *that*...

Ah - but that's not a serious challenge; that's as easy as memorizing
E.A.Poe's "The Raven" (sort of), plus a few words...

Clearly you have never had The Rhyme of the Ancient Mariner inflicted

Kate does 116 if I have counted correctly:

To be explicit, that's *not* the definition of an algebraic number.

Really? I was sure an algebraic number is any number computable using
only addition, subtraction, multiplication, division and extraction of
roots.

It's an interesting fact. However, at one point, it occured to me that
we take radicals for granted as computable. Consider sqrt(2). Somehow,
we're OK with expressing a number as "the number which, when squared,
equals two." Yet, we have no way of expressing it otherwise. We've all
seen approximations to this number, we would recognize it if we saw the
first few digits, yet we can't actually communicate it without
describing it in terms of the solution to x*x = 2. (There may be other
properties it has that we could use to describe it, but we still can't
just write it down and point to it, like we can with, say, an integer.
We can never find its precise value, we can only approximate it.)
So, it's kind of interesting that when we can't come up with a way to
describe a number besides "one of the roots of this degree-5
polynomial," we typically consider that less descriptive than the value
of an expression with radicals.
