Vexillology Memes

Genius mathematical wordplay at work! The flags of Cuba and Puerto Rico look nearly identical but with inverted colors—just like a function f(x) and its inverse f -1 (x) are mathematical reflections of each other. In calculus, when you take a function and flip it across the line y=x, you get its inverse function. Similarly, Cuba's flag has a red triangle with blue stripes, while Puerto Rico's has a blue triangle with red stripes. Whoever created this spotted a perfect mathematical metaphor hiding in plain sight in Caribbean vexillology. The relationship between these nations just got exponentially more interesting!

Geography nerds unite! This is basically flag algebra at its finest. Someone turned national flags into mathematical equations and it's ridiculously satisfying! Denmark + Finland = Norway? Absolutely checks out! The pattern continues with Poland × Japan = Greenland and gets increasingly complex. My favorite is the USA - (Somalia × 49) = Liberia equation, which is basically saying "remove all those stars and you've got Liberia!" It's like vexillology (the study of flags) had a wild night with mathematics and this beautiful nonsense was born. Now I'm just sitting here trying to create my own flag equations... Lebanon is particularly clever with that perfect tree placement!
