The beauty of biconditionals is you don't need to prove the converse separately - it's baked into the definition! Even parallel lines know this relationship goes both ways. 😂

The mathematical trauma is real! In logic and math proofs, the dreaded "if and only if" statement ( ) requires proving BOTH directions separately. The left side (=>) shows a utopian future where everything just works beautifully—like proving "if A then B." But the right side (
