## Math Notation Help

This glossary will help you build complex mathematical equations using the Tex markup language. This will involve using @@ or $$ before and after the expression to display the desired results.

## sum (summation)- General syntax for symbols with a kind of lower and upper limits:
\ - In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
- Syntax for summation symbol:
$$\bigsum_{i=k}^{n}$$ gives and $$\sum_{i=k}^{n}$$ gives - Use font size commands for a nicer picture:
$$\LARGE\bigsum_{\small{i=1}}^{\small{n}}$$ gives and $$\large\sum_{\small{i=1}}^{\small{n}}$$ gives | ||

## superscript- The command character "^" triggers superscription of the following expression(s).
- For more than one superscripted character put them in braces {...}.
- Use font sizing commands for appropriate sizing.
__Ex.:__$$x^2$$ gives
__Ex.:__$$a^{m+2n}$$ gives
__Ex. (with specific sizing):__$$x^{\small2}=a^{\small{m+2n}}$$ gives
- Combine superscripting with subscripting (command character "_").
Syntax: Expr_{subExpr}^{supExpr}. __Ex.:__$$A_{\small{i,j,k}}^{\small{-n+2}}$$ gives
