The other important part of that at least in my school, we had to use a graphing calculator but were also not allowed to use certain models that made things too easy.

That’s exactly my concern here.

Once you’re taking algebra it should be a assumption that given the time you can do basic multiplication, division, square roots and others given enough time but there isn’t any point when the more important part is solving other issues. That’s the simple stuff so why not make that easier as long as you learned how to get where you need to get.

But can you imagine having a tool like this when taking data structures?!?
