The "math tags" ( ... ) normally cannot contain any substitutable text, because of the order in which the wiki engine evaluates its input. This is most noticeable in a template, such as {{Lsym1}}, which is designed to show how LaTeX renders text, followed by the code used to generate the text. In the template, appears inside the math tags, with the idea that the parameter will be expanded before the LaTeX code is evaluated. However, the wiki engine does it in the other order: the is literally interpreted as LaTeX code, which, coincidentally, is meaningful to LaTeX. The curly braces are stripped off, leaving the value 1, which is dutifully rendered, regardless of the code actually intended.
