"If a ≡ b (mod n) and c ≡ d (mod n), then ac ≡ bd (mod n)." Varner would write it, tap the chalk once, and move on. The class nodded. Leo sank. elementary number theory burton 7th edition pdf.zip

So here he was, in his dorm’s musty basement laundry room (the only place with reliable Wi-Fi at this hour), staring at a link that glowed like a holy relic: "I—" Leo was a second-year math major, and
He read until dawn. Through the Euclidean algorithm ("like peeling an onion"). Through the linear Diophantine equation (ax + by = c). When the sun hit the barred window, he was on Chapter 5: Fermat’s Little Theorem. The proof felt like a door swinging open.
