No, you're grossly misrepresenting what I said. I never accused you of being poorly educated; in fact quite the opposite. I was ~100% sure you had seen vectors and complex numbers before and I was telling you this is exactly like what you have already seen. That's not an accusation of poor education, that's literally the opposite: pointing out that you're well educated enough to have seen that before.

I didn't intend that to be rude, I was pointing out this is something everyone learns in a standard curriculum i.e. that this is very much the opposite of esoteric. But you seemed determined to reply rudely, so I'll stop here.
