I introduced the word "vinculum" to my Math classes, and
told them that this word refers to the fraction bar. A student asked
where this name came from. I am thinking of making this an extra credit
projectm but would like to know myself. I have searched the Web, but
would like a condensed report on the history of this word. Thaks for
your immediate reply to this question.
In Latin, the word "vinculum" means "chain".
