Studying "Naive set theory" I've noticed that the symbol
usually adopted to mean : "item x belongs to set A" which
should resemble x C A (where I used C since I cannot draw
how it actually is, but imagine a semi-circle open to the
right with an horizontal - in the middle)is instead
represented on my screen by a small closed square. Since
the symbols used for Union of sets or intersection of sets
are those always used, I suspect that my computer uses a
set of characters' codes different from Yours. Have I got
the real reason? Thanks a lot, Paolo de Magistris,Italy.
Please provide the code you entered when reporting problems. The code for the
"is in this set" symbol is "\in". Union and intersection, I think, are "\cup"
and "\cap", respectively.
Can the original reporter provide more information please?
