hao,
A number is an abstract entity that represents a quantity (of magnitude), and its origin is lost in the mists of time.
The use everyday, we are inseparable from them, but you've asked yourself why the numbers are as they are, why the 1 is 1, and 2 is 2 ,...? :? You know? if the answer is yes, Oh, vendita curiosity! I congratulate you;). But usually this curious fact escapes most (I say this from experience).
Over time we changed to write on a curb, soft, according to legend, the Arabic numerals are represented by the number of angles that are to be written.
Curious?
May the force be with you! ;)
