comment Why doesn't this definition of natural numbers hold up in axiomatic set theory?
@MartinArgerami I've personally seen very few issues with the mathematical articles on Wikipedia (other topics notwithstanding). You'll find mistakes and typos in any reference. I've seen mathematics textbooks that are full of typos (and unlike Wikipedia it's impossible for them to be fixed once the book is printed).

Wikipedia is a great place to learn mathematics.

@DanielV ah yes, you are right.

@DanielV it's strong induction without the base case.

It probably goes without saying that it's a poor choice for expressions that aren't in an indeterminate form ($\frac{0}{0}$, $\frac{\infty}{\infty}$, $0\cdot \infty$, $0^0$, etc.).

$$\lim_{x\to \infty}\frac{2^x}{3^x}$$ is even simpler.

How do you know one of the top 3 horses didn't come in second in one of the 25 races?

I'm guessing $z=y$.

comment When solving for eigenvector, when do you have to check every equation?
I don't think it makes sense to say "not all the equations in (3) are linearly independent". Linear independence is a property of a whole set, not of the elements of a set. It would be clearer to say "the equations in (3) are linearly dependent".

Put the equals in quotes and then pronounce it with finger quotes.
