    Yes I had found similar references myself, but neither they nor

    those above do work: If I insert <br>

    <br>

                        {{math|''x'' {{=}}

    −(''y''<sup>2</sup> + 2)}}<br>

    <br>

     (copied from the first link above) into a wiki article and press

    "Show preview" it just displays <font color="#ff0000">Template:math</font>

    in red. How do I activate this template?<br>
