@kumicota@akkoma.kumicota.moe it's a pic of a book where they're explaining combinatorics with repetition and show the formula, which contains a few factorials (which in math notation are written like, a letter followed by a !) and then, on the next line they say "Or in Spanish notation" and then all factorial have now "¡" at the beginning and "!" at the end. #ALT4you

@kumicota@akkoma.kumicota.moe actually, you wouldn't need the parentheses in spanish notation one, bc the 2¡a+b! would be same as 2(a+b)!
