 inequality

/in'i kwol"i tee/, n., pl. inequalities.1. the condition of being unequal; lack of equality; disparity: inequality of size.2. social disparity: inequality between the rich and the poor.3. disparity or relative inadequacy in natural endowments: a startling inequality of intellect, talents, and physical stamina.4. injustice; partiality.5. unevenness, as of surface.6. an instance of unevenness.7. variableness, as of climate.8. Astron.a. any component part of the departure from uniformity in astronomical phenomena, esp. in orbital motion.b. the amount of such a departure.9. Math. a statement that two quantities are unequal, indicated by the symbol = with a diagonal stroke; alternatively, by the symbol < , signifying that the quantity preceding the symbol is less than that following, or by the symbol > , signifying that the quantity preceding the symbol is greater than that following.[13751425; late ME < L inaequalitas. See IN^{3}, EQUALITY]

In mathematics, a statement of an order relationshipgreater than, greater than or equal to, less than, or less than or equal tobetween two numbers or algebraic expressions.Inequalities can be posed either as questions, much like equations, and solved by similar techniques, or as statements of fact in the form of theorems. For example, the triangle inequality states that the sum of the lengths of any two sides of a triangle is greater than or equal to the length of the remaining side. Mathematical analysis relies on many such inequalities (e.g., the CauchySchwarz inequality) in the proofs of its most important theorems.* * *
