WebAbstract. The following discussions and activities are designed to lead the students to practice their basic arithmetic skills by learning about clock arithmetic (modular arithmetic) and cryptography. Although somewhat lengthy (approximately 2 hours), the lesson can easily be separated into two lessons. Websome basic ideas of modular arithmetic. Applications of modular arithmetic are given to divisibility tests and to block ciphers in cryptography. Modular arithmetic lets us carry out algebraic calculations on integers with a system-atic disregard for terms divisible by a certain number (called the modulus). This kind of flapjack bubbie\\u0027s tummy acheWebModular arithmetic is basically doing addition (and other operations) not on a line, as you usually do, but on a circle -- the values "wrap around", always staying less than a fixed number called the modulus. To find, for example, 39 modulo 7, you simply calculate 39/7 (= 5 4/7) and take the remainder. flapjack black leather couch
