A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. Because no real number satisfies this equation, i is called an imaginary number. For the complex number a + bi, a is called the real part, and b is called the imaginary part. Despite the historical nomenclature "imaginary", complex numbers are regarded in the mathematical sciences as just as "real" as the real numbers, and are fundamental in many aspects of the scientific description of the natural world.
A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a set of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length. Each reference line is called a coordinate axis or just axis of the system, and the point where they meet is its origin, at ordered pair (0, 0). The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin.
A number is a mathematical object used to count, measure, and also label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels, for ordering, and for codes. In common usage, number may refer to a symbol, a word, or a mathematical abstraction.
A political spectrum is a system of classifying different political positions upon one or more geometric axes that represent independent political dimensions.
Property law is the area of law that governs the various forms of ownership and tenancy in real property and in personal property, within the common law legal system. In the civil law system, there is a division between movable and immovable property. Movable property roughly corresponds to personal property, while immovable property corresponds to real estate or real property, and the associated rights, and obligations thereon.
Personal property is generally considered property that is movable, as opposed to real property or real estate. In common law systems, personal property may also be called chattels or personalty. In civil law systems, personal property is often called movable property or movables – any property that can be moved from one location to another.
In mathematics, and more specifically in naive set theory, the domain of definition of a function is the set of "input" or argument values for which the function is defined. That is, the function provides an "output" or value for each member of the domain. Conversely, the set of values the function takes on as output is termed the image of the function, which is sometimes also referred to as the range of the function.
The Number of the Beast is a science fiction novel by American writer Robert A. Heinlein, published in 1980. The first (paperback) edition featured a cover and interior illustrations by Richard M. Powers. Excerpts from the novel were serialized in the magazine Omni.
Exponentiation is a mathematical operation, written as bn, involving two numbers, the base b and the exponent n. When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, bn is the product of multiplying n bases:
Ownership is the state or fact of exclusive rights and control over property, which may be an object, land/real estate or intellectual property. Ownership involves multiple rights, collectively referred to as title, which may be separated and held by different parties.
In property law, a title is a bundle of rights in a piece of property in which a party may own either a legal interest or equitable interest. The rights in the bundle may be separated and held by different parties. It may also refer to a formal document, such as a deed, that serves as evidence of ownership. Conveyance of the document may be required in order to transfer ownership in the property to another person. Title is distinct from possession, a right that often accompanies ownership but is not necessarily sufficient to prove it. In many cases, both possession and title may be transferred independently of each other. For real property, land registration and recording provide public notice of ownership information.
A lien is a form of security interest granted over an item of property to secure the payment of a debt or performance of some other obligation. The owner of the property, who grants the lien, is referred to as the lienee and the person who has the benefit of the lien is referred to as the lienor or lien holder.
In arithmetic, a quotient is the quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as a fraction or a ratio. For example, when dividing twenty by three, the quotient is six and two thirds. In this sense, a quotient is the ratio of a dividend to its divisor.
A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. It is the idealized version of a solid physical tin can having lids on top and bottom.
Columnarios are silver coins that were minted by Spain from 1732 to 1773 throughout its new colonies in present-day Latin America. While the majority of columnarios were struck in Mexico, smaller mints existed in Guatemala; Lima, Peru; Santiago, Chile; Potosí, Bolivia; and Colombia. The base denomination is an 8 reales coin. Other minor denominations included 4 reales, 2 reales, 1 real, and 1/2 real. The 8 reales coin is the predecessor to the American dollar. Before the United States Mint was in production, columnarios circulated, along with other coinage, in the US colonies, as legal tender until the middle of the 19th century.
Sacca word meaning "real" or "true". In early Buddhist literature, sacca is often found in the context of the "Four Noble Truths", a crystallization of Buddhist wisdom. In addition, sacca is one of the ten pāramitās or "most high" a bodhisatta must develop in order to become a Buddha.
Real estate investing involves the purchase, ownership, management, rental and/or sale of real estate for profit. Improvement of realty property as part of a real estate investment strategy is generally considered to be a sub-specialty of real estate investing called real estate development. Real estate is an asset form with limited liquidity relative to other investments, it is also capital intensive and is highly cash flow dependent. If these factors are not well understood and managed by the investor, real estate becomes a risky investment. The primary cause of investment failure for real estate is that the investor goes into negative cash flow for a period of time that is not sustainable, often forcing them to resell the property at a loss or go into insolvency. A similar practice known as flipping is another reason for failure as the nature of the investment is often associated with short term profit with less effort.
In mathematics, a rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. The set of all rational numbers, often referred to as "the rationals", the field of rationals or the field of rational numbers is usually denoted by a boldface Q ; it was thus denoted in 1895 by Giuseppe Peano after quoziente, Italian for "quotient".
Real estate is "property consisting of land and the buildings on it, along with its natural resources such as crops, minerals or water; immovable property of this nature; an interest vested in this (also) an item of real property, buildings or housing in general. Also: the business of real estate; the profession of buying, selling, or renting land, buildings, or housing."
It is a legal term used in jurisdictions whose legal system is derived from English common law, such as India, England, Wales, Northern Ireland, United States, Canada, Pakistan, Australia, and New Zealand.
