At the electronics stack exchange, I've created plenty of equations to explain something (example). The method to create good looking fractions or subscripts result in nice looking elements, but often are very difficult to read because of their size. Without increasing the browser zoom size, I sometimes can't read it at all. Is there a way to increase the font size of equations to make it more legible in normal zoom?
Somewhat off topic, could someone tell me what the equation editing language is called that is used on there? Is it Tex or LaTex or something else? Could someone link to a full manual on it? So far I've just been learning it through viewing other posts through the edit feature, a very cumbersome method.
