 This image shows some kind of formula that could be converted to TeX. The MediaWiki TeX interpreter generates either PNG images or simple HTML markup, depending on user preferences and the complexity of the expression. In future, as more browsers are smarter, it will be able to generate enhanced HTML or even MathML in many cases. Storing formulas as images makes it harder to change them. TeX also helps making sure that they all use the same font and size. A replacement has been proposed: $\left[ \begin{matrix} f_1\\ f_2 \end{matrix} \right] = \left[ \begin{matrix} k&-k\\ -k&k \end{matrix} \right] \left[ \begin{matrix} d_1\\ d_2 \end{matrix} \right]$ $\left[ \begin{matrix} f_1\\ f_2 \end{matrix} \right] = \left[ \begin{matrix} k&-k\\ -k&k \end{matrix} \right] \left[ \begin{matrix} d_1\\ d_2 \end{matrix} \right]$
