Definition talk:Upper Sum

This page was just changed to replace the \, command from between the dots in the interval. I just wrote a note about this on the main talk page. If I were even more paranoid than I was, I'd suspect that someone was deliberately inflicting minor acts of sabotage for the sole purpose of irritating people. :-) --prime mover 19:03, 18 March 2012 (EDT)
 * Sorry. I happened to remember the opposite of what you (prime mover) wrote on the talk page. I've fixed Lower Sum. Abcxyz 19:17, 18 March 2012 (EDT)
