So now you know...

How numerals 0 - 9 got their shape -
0 1 2 3 4 5 6 7 8 9
Do you know why numbers look like they do? Someone, at some point in time,
had to create their shapes and meaning.
Watch this short presentation and then you will know how our Arabic numbers
were originally created a very long time ago and what logic the people that
created them used to determine their shapes. It is really very simple and
You have to admire the intelligence of a person or people that created
something so simple and perfect that it has lasted thousands and thousands
of years and will probably never change.
When the presentation gets to the number "seven" you will notice that the7
has a line through the middle of it. That was the way the Arabic 7 was
originally written, and in Europe and certain other areas they still write
the 7 that way. Also, in the military, they commonly write it that way. The
nine has a kind of curly tail on it that has been reduced, for the most
part nowadays, to a simple curve, but the logic involved still applies.
