I understand that Python is in the Microsoft App Store now, but conda is not. Step one might be to get curl or wget and bash installed. Are admin rights required to get Windows Subsystem for Linux (WSL) installed? Apparently, 'certutil' can be used to download over http on Windows platforms: certutil.exe -urlcache -split -f " https://download.sysinternals.com/files/PSTools.zip"; pstools.zip Then download and install Miniconda: - https://docs.conda.io/en/latest/miniconda.html <https://docs.conda.io/en/latest/miniconda.html> - https://docs.anaconda.com/anaconda/install/silent-mode/ certutil.exe -urlcache -split -f " https://repo.anaconda.com/miniconda/Miniconda3-latest-Windows-x86_64.exe"; start /wait "" Miniconda3-latest-Windows-x86_64.exe /InstallationType=JustMe /RegisterPython=1 /S /D=%UserProfile%\Miniconda3 Then create an environment and install a few things: conda create -n maths jupyterlab spyder conda activate maths conda install -c conda-forge sympy gmpy2 matplotlib safe Then start jupyterlab or spyder or vscode, or IPython: jupyterlab spyder ipython # %logstart -o logged.inputandoutput.py But how do you plot 3d graphics in a terminal? In Jupyter notebooks, an object's _repr_html_ method will be called before just repr(object) (which calls __repr__) in order to get output for the notebook. TI-84 don't have CAS (because … not allowed because measuring) so that would be a cool demo. > That might help make you a convert if you're still thinking your > calculator might be the more capable device to reach for.
