Do you know how the Arabic numbers 1 to 9 came about?
Watch a fascinating, very instructive Powerpoint presentation telling the real score about their genesis. It was sent to me by Forum contributor Frank A.

Now it’s school time again so I thought of reposting the presentation here for the benefit of every student and teacher—and for everybody for that matter—who missed viewing it the first time around.
