Have u ever asked the question - why "1" is "one", 2 is "two"...?

Recently i read an email and found it quite interesting.So...would like to share with u guys..
As we all know that, the number 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).

But have u ever asked the question - why "1" is "one", "2" is "two"...?

What is the logic that exist in the arabic algorithms? Answer: THESE ARE ANGLES!
Look at these algorithms written in their primitive form...

And guys, the most interesting and intelligent of all...
