Fraction Bar NameDate: 12/14/96 at 11:15:40 From: J. McLaggan Subject: Name of the little line in a division question Hi, What is the name of the little line that separates the divisor from the dividend in a standard division question: a - <- that one there b Thanks, John Date: 12/17/96 at 12:55:37 From: Doctor Bombelli Subject: Re: name of the little line in a division question John, There was actually quite a lengthy discussion of this in a History of Math mailing list. Different people and nationalities used different terms (variety is the spice of life). A VINCULUM (binding) is one name. It was originally for things like a --- b-c but became good for single term numerator and denominators as well. The term when you write a fraction this way----> a/b is a SOLIDUS. Interesting books on this subject are "The Words of Mathematics, An Etymological Dictionary of Mathematical Terms Used in English", Steven Schwartzman, MAA 1994 or "A History of Mathematical Notation", Florian Cajori, Dover. -Doctor Bombelli, The Math Forum Check out our web site! http://mathforum.org/dr.math/ Date: 12/17/96 at 22:11:37 From: J.
