Interesting fact about numberssss.....
Have you ever thought why........ 1 means "one", and 2 means "two"?
The roman numerals are easy to understand but what was the logic behind the phonecian numbers?
It's all about angles !
It's the number of angles.
If one writes the numbers down (see below) on a piece of paper in their older forms, one quickly sees why.
An ancient phonecian manuscript explains this and I thought it to be fascinating.

Interesting theory, but not one that I particularly agree with. If 0 was written in the same form as the rest of the numbers in that diagram then it would look like a rectangle, since the rest of the numbers are usually curved just as is a 0. Plus, looking at the 2 angles that are marked on the 8 that are more than 90 degrees, if they are going to be marked, then why not mark the opposite angles on other numbers to the ones that are already marked?
Life is full of interesting, and sometimes unanswerable questions. Happy thinking :-)
