I wrote in haste. I did not mean to offend you.

I *DO* mean offense to academic teaching. They invent bogus situations with 3 batteries and 4 resistors, which I have never seen in decades of wiring stuff up. Yes, I have seen many multiple sources but they never look like they look on the Quiz.

You are far ahead of me on basic algebra, and I think determinants are stubborn insects. My actual math scores were never as good as yours, and I've lost even that.
