# How to use Dirac bra-ket notation [closed]

It is not enough to use the form <a|b>, I need the separate ket form |A>, which the math writer does not have since it insists that angle brackets exist only in pairs.

I can not use |A> = sum from and so on. It apparently does not know that the > is not part of the equals sign.

And I do not want to have to learn to use Tex instead of LibreOffice.

Thanks in advance.

Objection: the accepted “right” answer was to install an extension, while there is a solution without need for any extensions. Since I don't have enough karma yet, I only supplied another “right” answer as a comment to another reply below.
