compound inequality
... Solving Compound and Absolute Value Inequalities Solve an Absolute Value Inequality (>) You can interpret |a| > 2 to mean that the distance between a and 0 on a number line is greater than 2 units. To make |a| > 2 true, you must substitute numbers for a that are more than 2 units from 0. ...

Integer Compositions, Gray Code, and the Fibonacci Sequence
... Much as the usual binary code provides a way to represent integers in base 2, Gray Code is a binary encoding method, but with an additional valuable property the Gray Code representations of two consecutive integers differ by only one bit. For instance, the integer representations of zero to three in ...

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.
