When I enter one of the symbols #, & ,|,^ or _ I get an unexpected result or an error message. How can I use these symbols?
These symbols all have a special meaning in Math:
- The symbol # is used in stacks and matrices.
- The symbols & and | are used for logical and logical or.
- The symbols ^ and _ are used for subscripts and superscripts.
To use them in your formula you can put them in quotation marks, which means that you insert them as text.
If you want to use the symbol "|" you should consider whether the construction you need is one of the following:
- a divides b is used to typeset a| b.
- abs a is used to typeset |a|.
