Cryptography is the study of methods for sending secret messages.. It involves . encryption. , in which a message, called . plaintext. , is converted into a form, called . ciphertext. , that may be sent over channels possibly open to view by outside parties. The receiver of the ciphertext uses . Adding Integers. The sum of two positive integers is always positive. 5 4=9.. The sum of two negative integers is always negative. -5 (-3)= -8.. The sum of a positive integer and a negative integer is sometimes positive, sometimes negative and sometimes zero.. 6.3 . The student will. a) identify and represent integers;. b) order and compare integers; and. c) identify and describe absolute value of integers.. Above Sea Level. Sea Level. Below Sea Level.

Instead, look at . modular. exponentiation. I.e., . c. ompute [a. b. mod N]. Size of the answer < . Our goal. Cover basic number theory quickly!. Cover the minimum needed for all the applications we will study. Some facts stated without proof. Can take entire classes devoted to this material. Abstracting some of the ideas makes things easier to understand. Now we have learnt the basics in logic.. We are going to apply the logical rules in proving mathematical theorems.. Direct proof.
