And here is the Jupyter notebook solving the problems using computer algebra (CA).
The CA for the five problems was done using the Sympy module, the Python language, and a Jupyter notebook.

And finally, there’s photomath …
There is an app called photomath; I have the free version on my phone. The user takes a picture of a math problem (no typing) and the app solves the problem. I took a picture of my laptop screen, Problem #8, and the app solved for the two solutions (see screenshot).
Disclaimer: I would not recommend that kids even know about this app.
Something from the past, on this Mathpax blog.
