Here is the general page rank algorithm:
But of course there are simpler ways of explaining this:
PageRank relies on the uniquely democratic nature of the web by using
its vast link structure as an indicator of an individual page's value.
In essence, search engines interprets a link from page A to page B as a vote,
by page A, for page B. But search engines looks at more than the sheer volume
of votes, or links a page receives, they also analyse the page that
casts the vote. Votes cast by pages that are themselves "important"
weigh more heavily and help to make other pages "important".
