# The relation between numbers and angles

7,293 views

Published on

Indian numerals form the basis of the European number systems which are now widely used. However they were not transmitted directly from India to Europe but rather came first to the Arabic/Islamic people and from them to Europe. The story of this transmission is not, however, a simple one. Actually the arabs popularized these numbers. So, the numbers we all use (1, 2, 3, 4, etc.) are known as "arabic" numbers to distinguish them from the "Roman Numerals" (I, II, III, IV, V, VI, etc).

Now an interesting finding. Have you ever thought why ........ 1 means "one", and 2 means "two"?

It's all about angles ! Watch this slide show to know more.

• the relation between Arabic numbers and angles is too strong to dismiss, its like wining the lottery 10 times in a row !
Richard, the Indian numbers are very different from Arabic numbers, all that i could read about how today's numbers (Arabic numerals) are merely a 'brainless' transformation from Indian numerals seems to be simple attempts to explain something that we do not have enough evidence to clarify.

• It's maybe a lovely story but as far as I can research, not true!

Both Wikipedia and this, more authoritative site give a history of numbers, originating in India, rather than the Phoenicians.

A pity, as I said, a lovely story.

• I learned this in college. Now I am using it for my students. They are fascinated to learn this and are surprised at how numbers began. THANKS!

### The relation between numbers and angles

1. 1. 013456… 1 2 4 5 The Numbers
2. 2. 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
3. 3. 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.
4. 4. 013456… 1 2 4 5 Have you ever asked the question why 1 is “one”, 2 is “two”, 3 is “three”…..?
5. 5. 013456… 1 2 4 5 What is the logic that exist in the arabic algorithms?
6. 6. 013456… 1 2 4 5 Easy, very easy…! There are angles!
7. 7. 013456… 1 2 4 5 Look at these algorithms written in their primitive form and check it up! …
8. 8. 013456… 1 2 4 5 1 angle 2 angles 3 angles 4 angles
9. 9. 013456… 1 2 4 5 5 angles 6 angles 7 angles 8 angles
10. 10. 013456… 1 2 4 5 9 angles
11. 11. 013456… 1 2 4 5 And the most interesting and intelligent of all…..
12. 12. 013456… 1 2 4 5 Zero angle !
13. 13. 013456… 1 2 4 5 Moral of the story: It is never late to learn!
14. 14. 013456… 1 2 4 5 Share it with your friends…….
