So, I teach high school math and we use numworks graphing calculators. They've been excellent! However, I recently ran across an issue that shows you can't always trust what your calculator says.
Suppose you want to take the cube root of negative 230. You should get approximately -6.127. It is perfectly fine to take the cube root of a negative number and get a real result. However, if the calculator is in Complex/Cartesian mode for displaying complex numbers, you get approximately 3.063+0.306i. Simply moving the negative sign outside of the radical sign (again, this is just fine to do in high school), you get the correct answer as shown below.
I wonder what causes this?

Het schooljaar is begonnen, vele middelbarescholieren moeten verplicht een #GrafischeRekenmachine aanschaffen. Gelukkig is er sinds kort een #opensource alternatief voor het TexasInstruments apparaat, de #numworks 🤓 , goedgekeurd door het College voor Toetsen en Examens ✅.

Tinkering in #python on the #numworks calculator. I've written a script that creates a template for truncated cones. It's useful for #rocket design when creating transitions between different diameter body sections. You can play with script, or download it to your numworks calculator from here https://my.numworks.com/python/concretedog56/transition_calculator although... it would probably happily run on any little python device like a @Raspberry_Pi pico etc. #rocketry

Quelle est la meilleure marque de calculatrice en France ?
La #NumWorks n'existe pas pour l'IA 😬 -

Just knocked up a little video of my early impressions of the #numworks N0120 #calculator I bought the other day! #maths #python
