Languages of South America - Thematic map

"Spanish and Portuguese are the most spoken languages in South America, with approximately 200 million speakers each. Spanish is the official language of most countries, along with other native languages in some countries. Portuguese is the official language of Brazil. Dutch is the official language of Suriname; English is the official language of Guyana, although there are at least twelve other languages spoken in the country, including Hindi and Arabic. English is also spoken in the Falkland Islands. French is the official language of French Guiana and the second language in Amapá, Brazil.
Indigenous languages of South America include Quechua in Ecuador, Peru, Chile, Argentina, Colombia, and Bolivia; Wayuunaiki in northern Colombia (La Guajira); Guaraní in Paraguay and, to a much lesser extent, in Bolivia; Aymara in Bolivia, Peru, and less often in Chile; and Mapudungun is spoken in certain pockets of southern Chile and, more rarely, Argentina. At least three South American indigenous languages (Quechua, Aymara, and Guarani) are recognized along with Spanish as national languages." [South America. Wikipedia]

"The Andean States are a group of nations in South America that are defined by sharing a common geography (Andes mountain range) or culture such as the Quechua language and Andean cuisine which was primarily spread during the times of the Inca Empire, but also before and after it.
Politically speaking, Argentina and Chile are usually not considered part of the Andean States as they lack a strong native Andean heritage and are culturally more oriented towards Europe and they are not a members of the Andean Community of Nations (which Venezuela is in the process of leaving).
The Andes occupy the western part of South America, stretching through the following countries: Colombia, Venezuela, Ecuador, Peru, Bolivia, Argentina (not considered to be -geopolitically- an Andean State), Chile (not considered to be -geopolitically- an Andean State)." [Andean states. Wikipedia]
"Southern Cone (Spanish: Cono Sur, Portuguese: Cone Sul) is a geographic region composed of the southernmost areas of South America, south of and around the Tropic of Capricorn. Traditionally, it covers Argentina, Chile and Uruguay, bounded on the west by the Pacific Ocean, and south to the junction between the Pacific and Atlantic Oceans, which is the closest continental area of Antarctica (1000 km). In terms of social and political geography, the Southern Cone comprises Argentina, Chile, Paraguay, Uruguay, Southern Brazil and the Brazilian state of São Paulo.
High life expectancy, the highest Human Development Index of Latin America, high standard of living, significant participation in the global markets and the emerging economy of its members make the Southern Cone the most prosperous macro-region in South America." [Southern Cone. Wikipedia]
Eastern South America (Brazil). "Brazil Listeni/ brəˈzɪl/ (Portuguese: Brasil, IPA: [bɾaˈziw]), officially the Federative Republic of Brazil (Portuguese: República Federativa do Brasil, About this sound listen (help·info)), is the largest country in both South America and the Latin American region. It is the world's fifth largest country, both by geographical area and by population. It is the largest Portuguese-speaking country in the world, and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 km (4,655 mi). It is bordered on the north by Venezuela, Guyana, Suriname and the French overseas region of French Guiana; on the northwest by Colombia; on the west by Bolivia and Peru; on the southwest by Argentina and Paraguay and on the south by Uruguay. Numerous archipelagos form part of Brazilian territory, such as Fernando de Noronha, Rocas Atoll, Saint Peter and Paul Rocks, and Trindade and Martim Vaz. It borders all other South American countries except Ecuador and Chile and occupies 47 percent of the continent of South America." [Brazil. Wikipedia]
"The Guianas, sometimes called by the Spanish loan-word Guayanas (Las Guayanas) refers to a region in north-eastern South America which includes the following three territories:
(1) French Guiana, an overseas department of France,
(2) Guyana, known as British Guiana from 1831 until 1966, after the colonies of Berbice, Essequibo, and Demerara, taken from the Netherlands in 1814, were merged into a single colony,
(3) Suriname, until 1814 a part of Dutch Guiana, together with Berbice, Essequibo and Demerara." [The Guianas. Wikipedia]

"In elementary algebra, a quadratic equation (from the Latin quadratus for "square") is any equation having the form
ax^2+bx+c=0
where x represents an unknown, and a, b, and c are constants with a not equal to 0. If a = 0, then the equation is linear, not quadratic. The constants a, b, and c are called, respectively, the quadratic coefficient, the linear coefficient and the constant or free term.
Because the quadratic equation involves only one unknown, it is called "univariate". The quadratic equation only contains powers of x that are non-negative integers, and therefore it is a polynomial equation, and in particular it is a second degree polynomial equation since the greatest power is two.
Quadratic equations can be solved by a process known in American English as factoring and in other varieties of English as factorising, by completing the square, by using the quadratic formula, or by graphing." [Quadratic equation. Wikipedia]
