A question to my knowledgeable readers: what's the correct way to represent a range of negative numbers? That is, if I have a table in which getting -1 through -2 yields one result and -3 through -5 yields another, how do I represent the ranges? I ask because it doesn't seem right that I should use "-1 - -2" and "-3 - -5." Do I use parentheses or brackets or some other way to separate the negative numbers from the dash between them?
Any help here would be appreciated. Thanks!
