Arithmetic or arithmetics (from the Greek word αριθμός = number) is the oldest and most elementary branch of mathematics, used by almost everyone, for tasks ranging from simple day-to-day counting to advanced science and business calculations, such as addition, subtraction, multiplication and division. In common usage, the word refers to a branch of (or the forerunner of) mathematics which records elementary properties of certain operations on numbers. Professional mathematicians sometimes use the term (higher) arithmetic when referring to number theory, but this should not be confused with elementary arithmetic. From Wikipedia under the

Asked by Las Vegas - Mon Oct 26 02:52:43 2009 - - 1 Answers - 0 Comments Under what conditions is the intersection of two arithmetic progressions an empty set? Q. I know that this is somehow related to the Chinese reminder theorem, but I cannot figure out the conditions under which the intersection of two arithmetic progressions A=a+(n-1)b B=c+(n-1)d have an empty intersection. Any ideas? Asked by John D is back - Sun Sep 20 04:11:43 2009 - - 1 Answers - 0 Comments A. If you get to demand that b and d are integers, then the answer is when b and d are not relatively prime (their greatest common factor is not 1), and (c - a) is not an integer multiple of the greatest common factor of b and d. Answered by unknown - Sun Sep 20 04:24:10 2009 How do you solve this arithmetic progression Q?
Q. An arithmetic series has a common difference of 7. Given that the sum of the first 20 terms of the series is 530, find i) the first term of the series, ii) the smallest positive term of the series. Ps. for i) I got a=397 is this correct? Asked by Chocolate - Sat Mar 28 06:39:33 2009 - - 3 Answers - 0 Comments A. Part 1 I hate remembering formulas, so try to think of the sum to n terms as the average of the first and last term multiplied by the number of terms. The first is a, the last is (a+19*7) Sum of the first 20 terms is (a + (a+19*7))/2 * 20 = 530 a=-40 Part 2 -40+(n-1)7 > 0 n > 6.71, meaning the 7th term would give you a positive number: Check the 7th term: -40 + 6*7 = 2 Sounds fine.
