Project Title: An Ancient Calculator



It is often wondered how ancient civilizations kept track of their food stock, population, or livestock. The Incas used a mechanism called a quipu, a device made of string tied in knots to represent a number, pronunciation key, or word. They could be added, subtracted, even multiplied and divided using complex matrix algebra, or they could tell a story of their history. Quipus are the only physical records today of the Incas. The goal in this project is to computerize the quipu and demonstrate the intricate minds of the Incas by manipulating matrices. The automated quipu will then be applied to jobs today such as accounting and booking.
