... 1. For each of the following a’s and b’s, use the Euclidean algorithm to compute d = gcd(a, b), and use the extended algorithm to find numbers u and v such that d = au+bv. (a) a = 1001, b = 9471. (b) a = 99958, b = 315905. (c) a = 117, b = 325. 2. Recall from class that gcd(a, b) = 1 if and only if ...

... i=1 Ci . Now as soon as C1 + C2 + . . . + Ck > 1, then S − (C1 + C2 + . . . + Ck ) ≤ 1. Hence C1 + C2 + . . . + Ck ≥ S − 1. Among these first k columns if any of them have sum less than S − 2 than it would be at most S − 3. If the column has sum, S − 3 then S − 3 = 1 or else it would be able to part ...

Arithmetic
Arithmetic or arithmetics (from the Greek ἀριθμός arithmos, ""number"") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory and are sometimes still used to refer to a wider part of number theory.
