en dashes vs minus signs vs hyphens Hi Jack a user has queried this edit It does look as though you replaced his minus signs with hyphens as they had been before his edit Minus signs are longer than hyphens and a little shorter and horizontally placed lower I think than en dashes Mathematicians are very fussy about them and the MoS insists on them in that context I checked with GregU the dash script inventor and he assured me it does insert minus signs not en dashes in such contexts
