For that it's best to look at how some other games do it, e.g.:<br /><br />- 1E Unearthed Arcana p. 15 (Cavaliers with negative XP) uses a large dash in the middle, with italicized numbers to set them off.<br />- 1E Unearthed Arcana 45 (Magic-users with negative XP for purpose of cantrips) uses the word "to" (although that's within text, not a table).<br />- 3E Player's Handbook p. 62 (example door DCs) uses the word "to" (even for positive numbers, no negatives included).<br /><br />Perhaps others can dig up more examples. Again, I would use "to".Deltahttp://www.blogger.com/profile/00705402326320853684noreply@blogger.comtag:blogger.com,1999:blog-7487871339000666216.post-178043744593678802010-12-14T23:53:17.452-05:002010-12-14T23:53:17.452-05:00Regardless of delimiters, it makes more sense to m...Regardless of delimiters, it makes more sense to me to write -5 to -2 rather than -2 to -5.

Note that this is my view as a consumer of roleplaying products and indicates my preferred mode based on readability, and is not based on any specific mathematical notation or rationale..<br /><br />(-1) - (-2) entry<br />(-3) - (-5) entry<br />(-6) - (-8) entry<br />(-9) - (-10) entry<br /><br />or something of the sort. If it were a positive range one would be used to seeing 1 - 2, 3 - 5, 6 - 8 (or whatever), and this seems consistent aesthetically.dhowarth333http://www.blogger.com/profile/18163514061779555557noreply@blogger.comtag:blogger.com,1999:blog-7487871339000666216.post-29186518714794497052010-12-14T18:45:00.001-05:002010-12-14T18:45:00.001-05:00The Excel-style colon is the most elegant if used ...The Excel-style colon is the most elegant if used consistently for positive ranges as well.

So −3 to −1 might be represented "−3 – −1". But it's not much of an improvement. (And in the font my web browser happens to render comments here in, it's not visible.)<br /><br />(I will note that the hyphen on your keyboard is likely neither an en-dash or a minus sign. The anal retentive among us appreciate using a proper minus sign in print. You can identify it because it's the same width as the plus sign.)Alan De Smethttp://www.blogger.com/profile/09091994420717419182noreply@blogger.comtag:blogger.com,1999:blog-7487871339000666216.post-61399490943080098212010-12-14T18:18:55.870-05:002010-12-14T18:18:55.870-05:00Mathematically speaking, if you want to represent ...Mathematically speaking, if you want to represent a closed set on a number line (i.e. you want to include the end points), then you would use brackets.
