Best ResponseYou've already chosen the best response.1Generally in linear algebra you need a double index to denote the row and column youre in (in reference to some matrix). Thats what those commas look like they are doing to me. \[a_{i,j}\]means the element in the ith row, jth column.

Best ResponseYou've already chosen the best response.3Actually, there is more of a context. Sometimes it denotes subscripts, however, it can also denote points on a parabola. In general, it is to separate quantities (e.g terms from their subscripts.)
