User blog comment:AJZajac/Help request - tips on entering mathematical symbols into blog/@comment-32876686-20171024020740/@comment-1605058-20171024082444

Two notes: instead of using $$something$$ you can also use \(something\) to type up equations; one advantage of this is that you can still edit these in the visual mode of the editor.

Secondly, please don't use * for multiplication in LaTeX. It renders as \(*\) which already bears different important meanings in mathematics (for example convolution). \cdot is the command recommended for this.
