💡 Memory Trick: The open mouth of > and < always faces the bigger number — like a hungry crocodile eating the larger value!
💡 ≥ vs >: "At least 18" means 18 is OK → use ≥. "Above 18" means 18 is NOT OK → use >.
💡 ≤ vs <: "Up to 10 kg" means 10 is OK → use ≤. "Under 10 kg" means 10 is NOT OK → use <.
