Square (algebra)
In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9. In some cases when superscripts are not available, as for instance in programming languages or plain text files, the notations ''x''^2 ( caret) or ''x''**2 may be used in place of ''x''2. The adjective which corresponds to squaring is ''quadratic''. The square of an integer may also be called a square number or a perfect square. In algebra, the operation of squaring is often generalized to polynomials, other expressions, or values in systems of mathematical values other than the numbers. For instance, the square of the linear polynomial is the quadratic polynomial . One of the important properties of squaring, for numbers as well as in many other mathematical systems, is that (for all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Square Number
In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it equals and can be written as . The usual notation for the square of a number is not the product , but the equivalent exponentiation , usually pronounced as " squared". The name ''square'' number comes from the name of the shape. The unit of area is defined as the area of a unit square (). Hence, a square with side length has area . If a square number is represented by ''n'' points, the points can be arranged in rows as a square each side of which has the same number of points as the square root of ''n''; thus, square numbers are a type of figurate numbers (other examples being cube numbers and triangular numbers). Square numbers are non-negative. A non-negative integer is a square number when its square root is again an integer. For example, \sqrt = 3, so 9 is a squ ...

Town Square
A town square (or square, plaza, public square, city square, urban square, or ''piazza'') is an open public space, commonly found in the heart of a traditional town but not necessarily a true geometric square, used for community gatherings. Related concepts are the civic center, the market square and the village green. Most squares are hardscapes suitable for open markets, concerts, political rallies, and other events that require firm ground. Being centrally located, town squares are usually surrounded by small shops such as bakeries, meat markets, cheese stores, and clothing stores. At their center is often a well, monument, statue or other feature. Those with fountains are sometimes called fountain squares. By country Australia The city centre of Adelaide and the adjacent suburb of North Adelaide, in South Australia, were planned by Colonel William Light in 1837. The city streets were laid out in a grid plan, with the city centre including a central public s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Square
In Euclidean geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, π/2 radian angles, or right angles). It can also be defined as a rectangle with two equal-length adjacent sides. It is the only regular polygon whose internal angle, central angle, and external angle are all equal (90°), and whose diagonals are all equal in length. A square with vertices ''ABCD'' would be denoted . Characterizations A convex quadrilateral is a square if and only if it is any one of the following: * A rectangle with two adjacent equal sides * A rhombus with a right vertex angle * A rhombus with all angles equal * A parallelogram with one right vertex angle and two adjacent equal sides * A quadrilateral with four equal sides and four right angles * A quadrilateral where the diagonals are equal, and are the perpendicular bisectors of each other (i.e., a rhombus with equal diagonals) * A convex quadrilatera ...

Fielding (cricket)
Fielding in the sport of cricket is the action of fielders in collecting the ball after it is struck by the striking batter, to limit the number of runs that the striker scores and/or to get a batter out by either catching a hit ball before it bounces, or by running out either batter before they can complete the run they are currently attempting. There are a number of recognised fielding positions, and they can be categorised into the offside and leg side of the field. Fielding also involves preventing the ball from going to or over the edge of the field (which would result in runs being scored by the batting team in the form of a boundary). A ''fielder'' or ''fieldsman'' may field the ball with any part of his body. However, if while the ball is in play he wilfully fields it otherwise (e.g. by using his hat), the ball becomes dead and five penalty runs are awarded to the batting side, unless the ball previously struck a batter not attempting to hit or avoid the ba ...

Cricket
Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of which is a pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by striking the ball bowled at one of the wickets with the bat and then running between the wickets, while the bowling and fielding side tries to prevent this (by preventing the ball from leaving the field, and getting the ball to either wicket) and dismiss each batter (so they are "out"). Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, and by the fielding side either catching the ball after it is hit by the bat, but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease in front of the wicket. When ten batters have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match r ...

Squares (crisps)
Squares formerly known as Square and Square Crisps are a British brand of square-shaped crisps made by Walkers, a subsidiary of PepsiCo. They were originally made by The Smith's Snackfood Company. History The crisps have been around since at least the 1980s and went under the name of Square Crisps. Several of their advertisements featured the comedian Lenny Henry and were marketed with slogans such as "more of a crunch than a crisp" and "the crisp that isn't a crisp". Following PepsiCo's acquisition of both Walkers and Smiths in 1989 Square Crisps were renamed to simply Square, and labelled as potato snacks. The product remained under the Smiths brand years after its fellow products Quavers and Monster Munch were moved to the Walkers brand. In January 2001, Walkers announced to relaunch Square, and would transition it from the Smiths brand to the Walkers brand. The name of the crisps was changed to Squares shortly afterward.

Square (band)
Square was a short-lived musical trio from Lincoln, Nebraska who moved to Southern California in early 2000. It was composed of Sean Beste (vocals and keyboards), James Valentine (guitars) and Ryland Steen (drums). Their sound has been described as including elements of rock, pop, and jazz fusion. The band moved to Orange County after entering an Ernie Ball-sponsored band competition. They won the grand prize, beating 600 other entrants. Shortly after winning the competition, they released their only full-length album, ''This Magnificent '', on an indie label called ''Lucy Smith Music''. The band started playing many gigs in the area, including some with local band Kara's Flowers. In 2001, the members of Kara's Flowers asked Valentine to join their group, an invitation that he accepted, effectively dissolving Square. Kara's Flowers changed its name to Maroon 5 Maroon 5 is an American pop rock band from Los Angeles, California. It currently consists of lead vocalis ...

Square (financial Services)
Square is a financial services platform developed by Block, Inc. It is aimed at small-and medium-size businesses, allowing them to accept credit card payments and use tablet computers as payment registers for a point-of-sale system. History The inspiration for Square occurred to Jack Dorsey in 2009 when his friend Jim McKelvey was unable to complete a $2,000 sale of his glass faucets and fittings because he could not accept credit cards. At the TechCrunch Disrupt conference in May 2011, Square announced the release of two apps, Square Card Case (later rebranded Square Wallet) and Square Register. Square Wallet, before it was removed from the Apple App Store and Google Play Store in 2014, allowed customers to set up a tab and pay for their order by providing their name (or a barcode) using a stored credit, debit, or gift card. In April 2012, rival payment company Verifone claimed that the Square system was insecure and that a reasonably skilled programmer could write a replaceme ...
