SUMMARY / RELATED TOPICS

In mathematics an operand is the object of a mathematical operation, i.e. it is the object or quantity, operated on. The following arithmetic expression shows an example of operators and operands: 3 + 6 = 9 In the above example,'+' is the symbol for the operation called addition; the operand'3' is one of the inputs followed by the addition operator, the operand'6' is the other input necessary for the operation. The result of the operation is 9. An operand is referred to as "one of the inputs for an operation". Operands may be complex, may consist of expressions made up of operators with operands. × 2 In the above expression" is the first operand for the multiplication operator and'2' the second. The operand" is an expression in itself, which contains an addition operator, with the operands'3' and'5'. Rules of precedence affect which values form operands for which operators: 3 + 5 × 2 In the above expression, the multiplication operator has the higher precedence than the addition operator, so the multiplication operator has operands of'5' and'2'.

The addition operator has operands of'3' and'5 × 2'. Depending on the mathematical notation being used the position of an operator in relation to its operand may vary. In everyday usage infix notation is the most common, however other notations exist, such as the prefix and postfix notations; these alternate notations are most common within computer science. Below is a comparison of three different notations — all represent an addition of the numbers'1' and'2' 1 + 2 + 1 2 1 2 + In a mathematical expression, the order of operation is carried out from left to right. Start with the leftmost value and seek the first operation to be carried out in accordance with the order specified above. For example, in the expression 4 × 2 2 −,the first operation to be acted upon is any and all expressions found inside a parenthesis. So beginning at the left and moving to the right, find the first parenthesis, that is. Within the parenthesis itself is found the expression 22; the reader is required to find the value of 22 before going any further.

The value of 22 is 4. Having found this value, the remaining expression looks like this: 4 × 2 2 − The next step is to calculate the value of expression inside the parenthesis itself, that is, = 6. Our expression now looks like this: 4 × 2 2 − 6 Having calculated the parenthetical part of the expression, we start over again beginning with the left most value and move right; the next order of operation is exponents. Start at the left most value, that is, 4, scan your eyes to the right and search for the first exponent you come across; the first expression we come across, expressed with an exponent is 22. We find the value of 22, 4. What we have left is the expression 4 × 4 − 6; the next order of operation is multiplication. 4 × 4 is 16. Now our expression looks like this: 16 − 6 The next order of operation according to the rules is division. However, there is no division operator sign in the expression, 16 − 6. So we move on to the next order of operation, i.e. addition and subtraction, which have the same precedence and are done left to right.

16 − 6 = 10. So the correct value for our original expression, 4 × 22 −, is 10, it is important to carry out the order of operation in accordance with rules set by convention. If the reader evaluates an expression but does not follow the correct order of operation, the reader will come forth with a different value; the different value will be the incorrect value. The reader will arrive at the correct value for the expression if and only if each operation is carried out in the proper order; the number of operands of an operator is called its arity. Based on arity, operators are classified as nullary, binary, etc. In computer programming languages, the definitions of operator and operand are the same as in mathematics. In computing, an operand is the part of a computer instruction which specifies what data is to be manipulated or operated on, while at the same time representing the data itself. A computer instruction describes an operation such as add or multiply X, while the operand specify on which X to operate as well as the value of X. Additionally, in assembly language, an operand is a value on which the instruction, named by mnemonic, operates.

The operand may be a processor register, a memory address, a literal const

Calinda is a martial art, as well as kind of folk music and war dance in the Caribbean which arose in the 1720s. Calinda is the French spelling, the Spanish equivalent is calenda. Calinda is a kind of stick-fighting seen practiced during Trinidad & Tobago Carnival, it is the national martial art of Tobago. French planters with their slaves, free coloreds and mulattos from neighboring islands of Grenada, Guadeloupe and Dominica migrated to Trinidad during the Cedula of Population. Carnival had arrived with the French. After Emancipation of slavery, a lead vocalist or chantwell would sing call-and-response chants called lavways lionizing and cheering on champion stickfighters. There, Carnival songs are considered to be derived from calinda chants and "lavways"; this form of music evolved into the modern calypso. Before the Emancipation from slavery and its integration into Carnival, Calinda was used as a type of performance to provide ways of entertainment for slaves. Once the French came to Trinidad, stick fighters were no longer known as stick men but as boismen.

There were different factors involved in stick fighting, including a costume that the performers would have to wear and the gayelles they would fight in. There are special rituals that are done in the gayelle before the fight starts that include different ceremonial songs. Though it is more practiced as a dance because of the violent outcome of stick-fighting, its roots are still that of a martial art originating from Kingdom of Kongo, stick-fights still occur in Trinidad, they have been formalised into annual Carnival competitions. It is practiced in other parts such as Martinique. Or Guadeloupe. Kalenda is one name assigned to an Afro-Caribbean form of stick fighting as practiced in Haiti and entering the United States through the port city of New Orleans. Similar forms of this martial art exist elsewhere in the Caribbean. For example, in Barbados it is referred to as "stick-licking" or "stick science." The well-known Cajun song "Allons danser Colinda" is about a Cajun boy asking a girl named Colinda to do a risqué dance with him.

Dancing the "Calinda" is referred to in one of Louisiana writer Kate Chopin's most famous stories from Bayou Folk, "La Belle Zoraïde," which stresses the strong Afro-Caribbean presence in Louisiana. Juego de maní Capoeira Bajan stick-licking Streetswing

Casajús or Casajús Winery, in Spanish: Bodegas Casajús, is a Spanish fine winery. It is situated in the town of Quintana del Pidio, in the Protected Designation of Origin Ribera del Duero. Over generations, the Calvo and Casajús families developed their own family wines, although it was not until 1993 that José Alberto Calvo Casajús founded the winery; the winery gained international recognition thanks to the great appraisals from the American wine magazine, Robert Parker’s The Wine Advocate upon reviewing Casajús Antiguos Viñedos and Vendimia Seleccionada, in particular the signature wine, NIC. José Alberto's grandparents, those of his wife Leonor, planted their vineyards in 1920, in Quintana del Pidio, in the heart of Ribera del Duero. Over generations, the Calvo and Casajús families developed their own wines in traditional cellars. In 1963, a local wine cooperative "Los Olmos" was founded in Quintana del Pidio, of which José Alberto and Leonor's families were founding and active members until the start of the 1990s.

In 1993 José Alberto left the local cooperative and founded his own winery in Quintana del Pidio: “Bodegas J. A. Calvo Casajús”, an activity that combined with José’s work as a baker. In 2004 production began of the signature wine, NIC, an acronym of his children's names, Nicolás and Catalina. In the middle of that same decade, the winery began to receive international recognition due to the positive reviews in Robert Parker’s The Wine Advocate. In 2013 the winery received the highest scores in Ribera del Duero from the British critic, Neal Martin, for the American magazine Robert Parker’s The Wine Advocate; the NIC 2009 wine was awarded 97 points and Casajús Viñedos Antiguos wine received 95 points, this triggered the receipt of international media attention. According to Robert Parker’s The Wine Advocate magazine: NIC 2009: 97 points. Antiguos Viñedos 2009: 95 points. Vendimia Seleccionada 2010: 94 points. Splendore 2010: 93 points. Valpidio 2011: 92 points. According to Wine Spectator magazine: NIC 2010: 95 points.
