Bro Memes

Linear algebra meets internet slang. Someone's written a matrix equation where "Bro Bro" multiplied by "Bro Bro" equals "Bro" times the identity matrix. Mathematically, this implies "Bro" is its own inverse, which is only possible if "Bro" equals 1 or -1. Congratulations, you've discovered the fundamental constant of the broverse. Your professor will still mark it wrong, but you'll be a legend in the group chat.
