Simple Examples
This section introduces the usage of the LaTeX2Markdown tool, showing an example of the various environments available.
Theorem 1 (Euclid, 300 BC)
There are infinitely many primes.
Proof
Suppose that $p_1 < p_2 < \dots < p_n$ are all of the primes. Let $P = 1 + \prod_{i=1}^n p_i$ and let $p$ be a prime dividing $P$.
Then $p$ can not be any of $p_i$, for otherwise $p$ would divide the difference $P - \left(\prod_{i=1}^n p_i \right) - 1$, which is impossible. So this prime $p$ is still another prime, and $p_1, p_2, \dots p_n$ cannot be all of the primes.
Exercise 1
Give an alternative proof that there are an infinite number of prime numbers.
To solve this exercise, we first introduce the following lemma.
Lemma 1
The Fermat numbers $F_n = 2^{2^{n}} + 1$ are pairwise relatively prime.
Proof
It is easy to show by induction that [ F_m - 2 = F_0 F_1 \dots F_{m-1}. ] This means that if $d$ divides both $F_n$ and $F_m$ (with $n < m$), then $d$ also divides $F_m - 2$. Hence, $d$ divides 2. But every Fermat number is odd, so $d$ is necessarily one. This proves the lemma.
We can now provide a solution to the exercise.
Theorem 2 (Goldbach, 1750)
There are infinitely many prime numbers.
Proof
Choose a prime divisor $p_n$ of each Fermat number $F_n$. By the lemma we know these primes are all distinct, showing there are infinitely many primes.

\begin{lem}
The Fermat numbers $F_n = 2^{2^{n}} + 1$ are pairwise relatively prime.
\end{lem}
\begin{proof}
It is easy to show by induction that
$$ F_m - 2 = F_0 F_1 \dots F_{m-1}. $$
This means that if $d$ divides both $F_n$ and $F_m$ (with $n < m$), then $d$ also divides $F_m - 2$. Hence, $d$ divides 2. But every Fermat number is odd, so $d$ is necessarily one. This proves the lemma.
