Google Page Rank Calculation

What is the page rank calculation?

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

PR= page rank
d= dampening factor (~0.85)
c = number of links on the page
PR(T1)/C(T1) = page rank of page 1 divided by the total number of links on page 1, (transferred page rank)

In text: for any given page A the PageRank PR(A) is equal to the sum of the parsed partial PageRank given from each page pointing at it multiplied by the dampening factor plus one minus the dampening factor.
