double prime

How would I proceed to add a double prime or triple prime to an identifier? The normal prime is easy to add.

Thank you for your question.
It seems Firemath need an additional feature. In fact, inspecting the MathML standard definition at the W3C web site I couldn't find any recommendation on how to add primes. I found one example on the web at
http://dlmf.nist.gov/2/4/#SS4
The solution there seems to be reasonable but I am not sure yet about the best way to incorporate that into Firemath.

In the meantime, what you can do is as follows. Add sub-superscripts to your variable. Move the cursor onto the superscript. Insert two apostrophes into the text-field and insert these as operators.

I am surprised they use ′ and not ″ for the double prime, or (for MathML 2 only?) tprime for triple prime ().

With the recent release of version 0.3.2 Firemath supports double, triple and quad primes, now.
