    When I enter one of the symbols #, & , |, ", %, ^ or _ I get an error message or an undesired result. How can I use these symbols?

    These symbols have special meanings in Math:

    • The # symbol is used with stack and matrix.
    • The symbols & and | are used to indicate logical and and logical or, respectively.
    • The symbol " is used to indicate strings of characters.
    • The symbol % is used to indicate a predefined symbol name or a personal symbol as explained in this FAQ.
    • The symbols ^ and _ are used to indicate superscripts and subscripts, respectively.

    To use one of these symbols in a formula, put it in quotation marks. For example: "#". There is one exception: double quotes can not put itself between quotes. To be displayed, you need to insert an escape character \ before:

    "\""
    

    There are two uses of the | symbol for which Math has specific markup:

    • a divides b will display a | b
    • abs a will display |a|

    Another solution would be to add an additional personal symbol as explained in this FAQ.
