If you wish to display math content together with inline text, use
...some text [math]A = \left\{ a_{1}, ..., a_{n} \right\}[/math]! some more text...
The reason why !
should be excluded from the math content – in that particular spot – is because it is an active character within the plugin. If a math expression starts with !
, it turns it into a display equation. If it ends with !
, it suppresses the formula output.
