Divisibility & Modular Arithmetic
Apply divisibility rules, work with modular arithmetic, and solve congruences
📖Khalid is a cryptographer. He uses modular arithmetic to encode messages. To decode, he needs to find remainders and solve congruences — the foundation of modern encryption!
🧠Fun Fact
Modular arithmetic is the backbone of RSA encryption, which secures most internet transactions. It was invented in 1977!
