If so, this is the wrong kind of itersection; streets ain't sets (well, I suppose you could ....).

The intersection of streets is much more common in daily parlance than the intersection of sets, so I think it should have a short word. A street can be regarded as the set of points along it, so the intersection of two streets is the set of points they have in common, which is what's normally meant, barring the complication of trying to figure out whether a point in the fillet is in the street. (I doubt that Trade and Tryon are filleted; filleting rights-of-way wasn't done on old maps.)

OT: I was in Raleigh with my mother in a clothing store. I asked some saleslady, "Pardon me for being from Charlotte, but where's the Tryon room?"

It does, "kruca".

Well, the intersection is strictly {le te kruca} and that seems to be about the right length. On the other hand, it does seem strange to use cmavo space for all this set notation (Cartesian products are even rarer). I suppose the idea is that mathematics — when someone gets around to doing it in Lojban — will expect words to match the notation. I am not sure why, since all anatural languages seem to manage with it (this goes for all of MEX as well).

## jo'e & ku'a formal definitiona

The formal definitions of jo'e and ku'a given actually describes some subset of the X∪Y and X∩Y respectively. They could be better defined as {lo selcmi noi da cmima gonai ke'a gi **X** .a **Y**}, and similarly with .e for ku'a. As it has an air of official-ness about it, I wasn't sure whether to just change it on the main page. 4D enthusiast (talk) 06:14, 26 August 2015 (PDT)
