I remember when we were learning about negative numbers I got it intuitively and was able to do all the problems right away. The teacher asked me to explain what I was doing and when I did he scolded me in front of everyone for not explaining it the way he did. I had said something like “the negative and positive cancel each other out” and whatever you’re left with is the answer. I don’t even remember what the “proper” explanation was but that’s always worked for me. I had a ton of moments like that with shitty math teachers over the last 4-5 years of grade school it really made me hate the subject. My 8th grade teacher hated me so much that she recommended me for the remedial math class in high school even though I was never having problems learning anything in her class I just didn’t do the obscene amount of homework she gave me. High school was better but I was a year behind everyone else because of that. The only plus to it was she also recommended like all the hot girls for that so I was in math classes with them for most of highschool.
