# show() for equations is not working

This might be a recurrent problem with Sagemath since I saw a previous question and its answer. That answer does not work in my case.

I just want to see equations rendered since it is easier to see if they are correct. The previous answer told us to add a sys. stdout.flush() command line after each show

- import sys
- sys.stdout.flush()
- var("x y z ")
- show(x**2)

This does not work in my system.

Any help would be welcome.

Thanks

The version on the repository is rather old. I would suggest that you install the latest version using conda/mamba easily following https://doc.sagemath.org/html/en/installation/conda.html#sec-installation-conda

I use SageMath on Debian 12, the version is 9.5 and the MathJax display of expressions works without problems, so it is not a problem related to the old version.
