Math Notation Help

• The command character "_" triggers subscription of the following expression(s).
• For more than one subscripted character put them in braces {...}.
• Use font sizing commands for appropriate sizing.
• Ex.:$$x_1$$ gives

$x_1$

• Ex.:$$a_{m+2n}$$ gives

$a_{m+2n}$

• Ex. (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

$A_{\small{i,j,k}}^{\small{-n+2}}$
