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 withstackandmatrix.
- The symbols &and|are used to indicate logicalandand logicalor, 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.
