# MathML Demo: <mmultiscripts> - attach prescripts and tensor indices to a base

A MathML mmultiscripts object allows you to build tensor-like objects. For example ${}_{a}{}^{b}M_{c}^{d}$. The scripts come in pairs, with `<mprescripts/>` used to indicate prescripts and `<none/>` used to hold an empty position as in ${}_{a}F^{b}$. There are some variations possible: `<mmultiscripts>` $A_{a}^{b}{}_{c}{}^{d}$, nested `<msubsup>`s ${{A}_{a}^{b}}_{c}^{d}$, or `&InvisibleComma;` $A_{a⁣c}^{b⁣d}$.
