Math that made Google rich…

Some mathematics that has made Google the richest (in results and $) search engine...

Google talks about "solving an equation of more than 500 million variables and 2 billion terms" for determining the PageRank of a particular Web page. PageRank is the process Google uses to determine the position of a Web page in a Google search result. It is determined by how many incoming links there are, where key words are on the page and the surrounding content.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

  1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
    `a^2 = sqrt(b^2 + c^2)`
    (See more on ASCIIMath syntax); or
  2. Use simple LaTeX in the following format. Surround your math with \( and \).
    \( \int g dx = \sqrt{\frac{a}{b}} \)
    (This is standard simple LaTeX.)

NOTE: You can mix both types of math entry in your comment.
