I enter x^* to typeset x*, but get an error message. Why?
The problem is that * is a binary operator, that is there has to be an expression on both sides of the symbol.
You either have to enter the expression x^{{}*{}} to avoid the error message, or you could type x^"*" as well, where the quotes will interpret the asterisk not as a binary operator but as a "standalone" symbol.
If you use this construction a lot you might want to define the symbol as an user defined symbol. See I need a symbol that Math does not provide. What can I do?. If you have defined the * as an user defined symbol, say %ast, you can enter x^%ast.
This answer applies to a lot of other symbols as well. Some operators, such as +, are unary, that is there only has to be an expression to the right of the symbol. To typeset x+ you can enter x^{+{}}< or, of course, x^"+".
I want to use a binary operator (like union or otimes) as a large operator (like int or sum). How can I do that?
You have to define the symbol you want to use as a user-defined symbol first. See <A HREF="012.html">FAQ #012</A> for instructions; most of the symbols used by Math are part of the StarMath font.
Let's say you have defined the union symbol as the user-defined symbol %union. You can then enter for example
oper%union from i in I A_i
in order to typeset the formula
Note: In build 633 this doesn't work if there is a space before %union (this is a bug in the parser).
Any user-defined symbol can be used as a large operator if it is preceded with oper as in the example.
