The perfect mathematical pun doesn't exi— Oh wait, here it is! This brilliant meme plays on complex numbers, where the famous soccer team Real Madrid gets the mathematical treatment. In math, complex numbers have both "real" and "imaginary" parts, with the imaginary component multiplied by i (the square root of -1). So naturally, the "imaginary madrid" logo has the square root symbol of -1 next to it! Soccer fans who failed calculus are probably scratching their heads right now while math nerds are quietly chuckling in the corner. The only thing more complex than these numbers is trying to explain to sports fans why this is hilarious.
