In mathematics, an equation is a statement that two mathematical expressions have the same value. Solving an equation is often the primary goal of algebraic solution. There are several types of equations that are used frequently in mathematics.

Introduction to Inequalities

In mathematics, an inequality is a statement that one number, in some sense, is greater than or less than another number. The "greater than" or "less than" may be "=" (identical), "<" (less than), or ">" (greater than).

Introduction to Inequalities - Example 1

In mathematics, an inequality is a statement that one quantity is greater than or less than another quantity. The notation a ? b means that a is not equal to b, i.e. a is not greater than b and a is not less than b. If there is no restriction on the values of a and b, then this is called an absolute inequality. If a < b, a > b, a ? b, or a ? b, then this is a relative inequality.

Unit Conversions - Overview

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity. The metre is a unit of length that represents a definite predetermined length. When we say 10 metres (or 10 m) we actually mean 10 times the definite predetermined length called "metre".

In mathematics, the distance between two points on a plane is the length of the shortest segment connecting them. It is a special case of the distance between two points in Euclidean space, where the segment may be replaced by a curve connecting the points. The distance between two points is a signed quantity, a positive distance representing movement in a positive direction from the first point to the second.

Functions - Overview

In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x, given by the rule for all real numbers x, (x) = x. The output of a function f corresponding to an input x is denoted by f(x) (read "f of x"), y, or f(x) (read "f of x", "f at x", or "f of x"). In this example, if the input is ?3, then the output is 9, and we may write f(?3) = 9, or simply f(?3) = 9. If the input variable, x, is represented by the letter "x", then the output variable, f(x), is sometimes represented by the letter "y" in functional notation, especially in computer science.
