When the presentation gets to the number "seven" you will notice that the 7 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; the military commonly write it that fashion also. The nine has a kind of curly tail on it that has been reduced to a simple curve, but the logic involved still applies.

It's really very simple and quite creative! You have to admire the intelligence of a person that created something so simple and perfect that it has lasted for thousands and thousands of years and will probably never change.
