The abacus‚ often called the earliest calculating machine in the world‚ has a long history. The earliest mention of the abacus can be dated back to the Eastern Han Dynasty‚ where it was mentioned in a book by Xu Yue in about 190 A.D‚ There was a time when numbers were not written. As larger numbers become needed past the amount on a human hand‚ various natural goods become items in the counting process. The history and evolution of the abacus is a long one and is often divided into three time periods

Rational Expressions: Simplifying Thinking back to when you were dealing with whole-number fractions‚ one of the first things you did was simplify them: You "cancelled off" factors which were in common between the numerator and denominator. You could do this because dividing any number by itself gives you just "1"‚ and you can ignore factors of "1". ADVERTISEMENT Using the same reasoning and methods‚ let’s simplify some rational expressions. • Simplify the following expression: To

GOOGLE’S ALGORITHM: ==Algorithm== PageRank is a [[probability distribution]] used to represent the likelihood that a person randomly clicking on links will arrive at any particular page. PageRank can be calculated for collections of documents of any size. It is assumed in several research papers that the distribution is evenly divided among all documents in the collection at the beginning of the computational process. The PageRank computations require several passes‚ called "iterations"‚
