Glib fast talking! Yes full of bullshit! The fact is that you have to learn the arithmetic facts first preferably in the +-x / order learn them, commit them to rote memory and no one will be hurt by this… and then get them going on the i41CX+ and teach them how to program in the simplest programming language of all. Yes, add in all this other interesting stuff too like interlocking torii. And why measurements are needed.
All of the crap of rote memory vs. so called “deep memory” is subversive and pernicious.
