    The comma is use in numbers and mathematics to make to numbers easier to read. ( avoid confusion )

    ironic cuzz it is confusing me I understand when it is a pair like x,y but what does it mean in the context of linear algebra?

    It's just to separate numbers and letters.

    Generally 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 i-th row, j-th column.

    Actually, 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.)
