We were being onboarded, they were just for demo and were promptly deleted. No one cared about the Cool Numbers.
1 + 2 + ... + n = n(n+1)/2
2 divides n(n+1), n(n+1) = 2m
7 * n^3 + n =
2*(3*n^3 + n) + n^3 - n =
2*(3*n^3 + n) + n(n+1)(n-1) =
2*(3*n^3 + n + m(n-1))
Got any experience with adapting fountain pen inks for calligraphy?
Plus, there's a question of how people use them, but that distinction I think came later
Your example expands well to old-school emoticons. Where I live, an "xD" serves as a laugh and is used in rather general way. Meanwhile in the Anglosphere it's stereotypically associated with specific demographics
