Humble Mathematician / @Humble Mathematician Even now, when I see someone who can handle university-level math, I have a lot of respect for them. I studied it in class when I was a university student, but I can't solve it at all... I kind of regret having crammed the night before. I never thought I'd reach an age where I'd think, "I should have studied more" (lol) Be careful not to regret it, and look forward to the Los Angeles edition too Sarueru◯ For work inquiries, please contact sekibuncircledx[@]gmail.com.
