The document discusses the origin and logic of the Arabic number system. It explains that the numbers 1-9 represent the number of angles in each symbol and zero represents no angles. The Arabic number system became popularized by Arabs but originated with Phoenician merchants who used it for counting and accounting. The overall system is based on a simple logic using the number of angles in each symbol.

013456 1 2 4 5 The Numbers
The numbers we write are made up of algorithms, (1, 2, 3, 4, etc) called arabic algorithms, to distinguish them from the roman algorithms (I; II; III; IV; etc.). 013456 1 2 4 5
013456 1 2 4 5 The arabs popularise these algorithms, but their origin goes back to the phenecian merchants that used them to count and do their commercial contability.
013456 1 2 4 5 Have you ever asked the question why 1 is one, 2 is two, 3 is three..?
013456 1 2 4 5 What is the logic that exist in the arabic algorithms?
013456 1 2 4 5 Easy, very easy! There are angles!
013456 1 2 4 5 Look at these algorithms written in their primitive form and check it up!
013456 1 2 4 5 1 angle 2 angles 3 angles 4 angles
013456 1 2 4 5 5 angles 6 angles 7 angles 8 angles
013456 1 2 4 5 9 angles
013456 1 2 4 5 And the most interesting and intelligent of all..
013456 1 2 4 5 Zero angle !
013456 1 2 4 5 Moral of the story: It is never late to learn!
