## 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.

(with specific sizing): $$x_{\small1}=a_{\small{m+2n}}gives x_{\small1}=a_{\small{m+2n}}$$ • Combine subscripting with superscripting (command character "^"). Syntax: Expr_{subExpr}^{supExpr}. • Ex.: $$A_{\small{i,j,k}}^{\small{-n+2}}gives A_{\small{i,j,k}}^{\small{-n+2}}$$ #### sum (summation) • General syntax for symbols with a kind of lower and upper limits: \symbolname_{lowerexpression}^{upperexpression} • 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: $$\bigsum_{i=k}^{n}gives \bigsum_{i=k}^{n} and \sum_{i=k}^{n} gives $\sum_{i=k}^{n}$ • Use font size commands for a nicer picture:$$\LARGE\bigsum_{\small{i=1}}^{\small{n}}gives \LARGE\bigsum_{\small{i=1}}^{\small{n}} and \large\sum_{\small{i=1}}^{\small{n}}$   gives

$\large\sum_{\small{i=1}}^{\small{n}}$

 Keyword(s): big sum

#### 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.: $$x^2gives x^2$$

• Ex.: $$a^{m+2n}gives a^{m+2n}$$

• Ex. (with specific sizing): $$x^{\small2}=a^{\small{m+2n}}gives x^{\small2}=a^{\small{m+2n}}$$

• Combine superscripting with subscripting (command character "_").
Syntax: Expr_{subExpr}^{supExpr}.
• Ex.: $$A_{\small{i,j,k}}^{\small{-n+2}}gives A_{\small{i,j,k}}^{\small{-n+2}}$$
