... An positive integer n is called perfect if it is the sum of all positive divisors of n less than n itself. It is not known if there are any odd perfect numbers, but all even perfect numbers have been classified according to the following lemma: Lemma 1. An even number is perfect if and only if it eq ...

... A function is a relation in which each element of the domain (the inputs, or x-values) of the relation corresponds to exactly one element in the range (the outputs, or y-values) of the function. Vertical Line Test A set of points in the xy-plane is the graph of a function if and only if every vertic ...

... In recent years, EBCDIC has been expanded to 16- and 32-bit variants to allow for representation of large, non-latin character sets. Each EBCDIC variant is known as a codepage, identified by its Coded Character Set Identifier, or CCSID. EBCDIC codepages have been created for a number of major writin ...

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.
