Hi.

At the moment, I am finishing the first hundred problems.
But when I try to read newer problems, I can't decrypt the problem descriptions
because they look like:
"$$\displaystyle g(n)=\sum_{i=1}^{n} (-1)^i \gcd \left(n,i^2\right)$$ "

I only see lots of dollar signs, backslashes, underscores etc. pp.
Can you please tell me, how to make the problem readable?

I am using Ubuntu Linux 10.04.4 LTS with PaleMoon 26.5.0 web browser.
I am a severally damaged person and not able to use modern computer.

Thanks a lot from Hamburg/Germany,

This site uses a library called MathJax which renders the content between the dollar signs into mathematical expressions. It's essentially a JavaScript implementation of the mathematics rendering part of the typesetting language TeX. If you see the raw markup then it probably means that you have JavaScript disabled.

MathJax has some accessibility support: see https://docs.mathjax.org/en/latest/basi ... ility.html for details.

If the problem is in fact MathJax compatibility with your browser and you want a visual representation rather than aural rendering, the site http://mathurl.com/ can render the markup into images server-side, which might solve the compatibility issue.

Great!
Thank you very much.
