For what this symbol "$"(Symbol of dollar) is used?

[localghost]

It is for writing math formulas in in-line math mode. I strongly recommend to do some basic reading [1]. Many questions are answered by studying the introduced documents.

It's used to begin and to end the math mode, for formulas embedded in text, like

Code: Select all

Mass–energy equivalence: $E = mc^2$.

I recommend to read some LaTeX introduction or tutorial to get basic information like this: LaTeX Resources for Beginners.
