... (2t-1)-(2s-1)= 2t-2s=2s(2t-s-1)=(q2- q1)m. ∵ m is odd, ∴ gcd(2s,m) =1. Hence m︳2t-s-1, and the result follows with n=t-s. Eg. An inventory consists of a list of 80 items, each marked “available” or ‘unavailable”. There are 45 available items. Show that there are at least 2 available items in the lis ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
