1. Equation

In mathematics, an equation is a formula of the form A = B, where A and B are expressions containing one or several variables called unknowns, and "=" denotes the equality binary relation. Although written in the form of proposition, an equation is not a statement, but a problem consisting in finding the values, called solutions, that, when substituted to the unknowns, yields equal values of expressions A and B. For example, 2 is the unique solution of the equation x + 2 = 4, in which the unknown is x. Historically, equations arose from the mathematical discipline of algebra, but later become ubiquitous. An equality may not be confused with identities which are presented with the same notation but have a different semantic: for example 2 + 2 = 4 and x + y = y + x are identities in arithmetic, and do not constitute any values-finding problem, even if include variables. Equation may also refer to a relation between some variables that is expressed by the equality of some expressions of their values. For example the equation of the unit circle is x² + y² = 1, which means that a point belongs to the circle if and only if its coordinates are related by this equation. Most physical laws are expressed by equations. One of the most popular ones is Einstein's equation E = mc².
