Maybe you got lucky then, because when I was a kid, rote memorization was the only way teachers would accept the answer. If you changed the problem to 10 + 6 or the one op posted, the teacher would tell you that you did it wrong. This is why I just decided to do this regrouping in my head and just write what the teacher wanted because I would get the right answer anyway and not get told it was wrong.
Oh yes very lucky!! I had some really amazing teachers. they really made me enjoy maths and science and all that hard shit, and rewarded that kinda thinking. Cause what you just mentioned is so demoralizing
Even had a maths teacher who was kinda a prick (for other reasons) but he was the one that encouraged that kinda thinking the most
Hmm no I’m not
