WebThe proofs in number theory are typically very clean and clear; there is little in the way of abstraction to cloud one's understanding of the essential points of an argument. Secondly, the integers have a central position in mathematics and are used extensively in other fields such as computer science. WebTo prove that a statement holds for all positive integers n, we first verify that it holds for n= 1, and then we prove that if it holds for a certain natural number k, it also holds for 1k+ . This is given in the following. Theorem 2.1. (Principle of Mathematical Induction) Let ( )Sndenote a statement involving a variable n. f16 worth

WebSolution We first notice that for d ∈ Z, we have: • If d is even, there exists k ∈ Z such that d = 2 k and d 2 = 4 k 2 so d 2 ≡ 0 mod 4. • If d is odd, there exists k ∈ Z such that d = 2 k +1 and d 2 = 4 k 2 +4 k +1 so d 2 ≡ 1 mod 4. Let a, b, c ∈ Z and assume for a contradiction that a 2 + b 2 = c 2 and a and b are both odd. WebThe Euclidean Algorithm is a technique for quickly finding the GCD of two integers. The Algorithm The Euclidean Algorithm for finding GCD (A,B) is as follows: If A = 0 then GCD (A,B)=B, since the GCD (0,B)=B, and we can stop. If B = 0 then GCD (A,B)=A, since the GCD (A,0)=A, and we can stop. Write A in quotient remainder form (A = B⋅Q + R)
