I'm confused: Algebraic Numbers
I'm reading this off a site
http://www.mathsisfun.com/numbers/algebraic-numbers.html
[quote]An algebraic number is any number that is a root of a non-zero polynomial with [b]rational coefficients. [/b]
Example: is √2 (the square root of 2) algebraic or transcendental?
√2 is the solution to x2 - 2 = 0, so is therefore algebraic
[/quote]
What? But √2 is [b]irrational![/b]
EDIT:
I get what a rational number is. I get what an irrational number is. But I don't get what an algebraic number is.
[quote]The root of an algebraic equation with rational coefficients.[/quote]
But I don't know what that's supposed to even mean!

To be honest math has been nothing but a pain ever since I started learning it. Every step of the way it's another brick wall and another thing that I can't comprehend. I don't want to learn math simply because I feel as though it's something I need to brush up on or because I need to take the SAT, but I think I keep putting myself between a rock and a hard place for the reason that I never finish anything that I start, and I want to for once keep my word that I can endure. Usually when the fire gets too hot I jump ship. Now I feel as though I'm burning alive. By now my brain is not even trying to understand algebraic numbers and I'm not sure I can. Even then I still have imaginary numbers, factoring, and other things that make my head explode.
