I would like to insert a formula in a Pages document (under El Capitan). But when I chose
Insert -> Formula in the menu all entries in the submenu all entries are greyed out. Also
Insert -> MathType equation is greyed out.
Do I need to install further software to have the options available?
I am looking for a way to typeset a mathematical formula in a document (i.e., a kind of formula editor). Does any tool like this come together with Apple's office tool?
