Full Transcript

These things only starting becoming a serious element of the mathematical landscape in the western world in the 18th century. So in fact long before the well-known "number line" model of arithmetic took hold in students' minds, there was a simpler, more fundamental arena for arithmetic. It turns out that this largely missing chapter is now taking centre stage in the new development of Box Arithmetic. ******* Research Gate page: https://www.researchgate.net/profile/Norman_Wildberger Blog: http://njwildberger.com/ Online courses at openlearning.com (currently Algebraic Calculus One): https://www.openlearning.com/courses/algebraic-calculus-one/ Please join us for an exciting new approach to one of mathematics' most important subjects!
