Here is a Wiki for primes and related topics, still under construction.

Examples in math (LaTeX) notation

<math>N \supset \mathbb P = \{ p_n \mid n \in N \}</math>

N \supset P = {p_{n} ∣ n \in N}

<math>\sideset{_1^2}{_3^4}\prod_a^b</math>

{}_{1}^{2}\prod_{3}^{4}_{a}^{b}

<math>\iiiint\limits_{F} \, dx\,dy\,dz\,dt</math>

\underset{F}{⨌} d x d y d z d t

<math>f(n) =
\begin{cases}
  n/2, & \mbox{if }n\mbox{ is even} \\
  3n+1, & \mbox{if }n\mbox{ is odd}
\end{cases}</math>

f (n) = {\begin{cases} n / 2, & if n is even \\ 3 n + 1, & if n is odd \end{cases}

<math>\sum_{i=1}^\infty \frac{1}{p_i} = \frac{1}{2} + \frac{1}{3} + \frac{1}{5} + \frac{1}{7} + \frac{1}{11} + \dotsb = \infty</math>

\sum_{i = 1}^{\infty} \frac{1}{p_{i}} = \frac{1}{2} + \frac{1}{3} + \frac{1}{5} + \frac{1}{7} + \frac{1}{11} + \dots = \infty

<math>\pi(1)=0\ ;\ \pi(10) = 4\ ;\ \pi(100) = 25\ ;\ \pi(1000) = 168; \ \pi(1000000)=78498</math>

π (1) = 0; π (10) = 4; π (100) = 25; π (1000) = 168; π (1000000) = 78498
