European 7Date: 8/15/96 at 20:51:53 From: Anonymous Subject: European 7 Why is the numeral seven sometimes written with a line through it in Europe? I've researched it in my encyclopedia and here and cannot find a reference. If you give me a reference, I'll research it. Thanks. Date: 8/16/96 at 13:27:44 From: Doctor Tom Subject: Re: European 7 The line is to distinguish it from the numeral "1". Most Europeans draw a "1" not with just a vertical line, but with a tiny stroke from the top and down to the left. If you're writing quickly, it's easy to mix it up with a "7". For similar reasons, I've seen people cross their "z"s to keep them from looking like the numeral "2". -Doctor Tom, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
