Modular Arithmetic | Road to RSA Encryption #6

This is the sixth video in a series of videos that leads up to the math of RSA Cryptography. This video series will cover the contents of the book "Number Theory Towards RSA Cryptography in 10 Undergraduate Lectures" available here: https://www.amazon.com/Number-Theory-Toward-Cryptography-Undergraduate/dp/1978457464 This content is covered in a Discrete Math course I often teach, and is usually covered in a stand alone Number Theory course at other institutions. In this video we cover modular arithmetic. We discuss the introductory properties of modular arithmetic, show how to reduce large powers of a given number by a given modulus, and give a proof of the rule for divisibility by 9 using modular arithmetic. #ModularArithmetic #ModularArithmeticRules #DivisibilityBy9 CHECK OUT OTHER TYPES OF VIDEOS: ================================ GRE Math Subject Test: https://www.youtube.com/playlist?list=PLBiVnG9A5gceFbk7oTBHALETI2SUmplIL Putnam Math Competition: https://www.youtube.com/playlist?list=PLBiVnG9A5gcdLg0Im3qewDrgcMxpbjcqN Math Theorem Corner: https://www.youtube.com/playlist?list=PLBiVnG9A5gccu9O8aCjVsynisfQLQyGOe Math Problems Corner: https://www.youtube.com/playlist?list=PLBiVnG9A5gcc_1Kzd2xkHMXdO8zHz-W_4 Math Insights: https://www.youtube.com/playlist?list=PLBiVnG9A5gcfHRbtZcfQdJuUMAS6v48uj Academic Advice: https://www.youtube.com/playlist?list=PLBiVnG9A5gce-PPdJQmtPNMsivAKKuXwe GET MY BOOK ON AMAZON!! ======================== "Number Theory Towards RSA Cryptography in 10 Undergraduate Lectures" https://www.amazon.com/Number-Theory-Toward-Cryptography-Undergraduate/dp/1978457464 CHECK ME OUT ON THE INTERNET!! ============================== TikTok: @profomarmath Website: www.mohamedomar.org Twitter: @ProfOmarMath Instagram: profomarmath YouTube: www.youtube.com/ProfOmarMath And of course, subscribe to my channel!
