Decimals: Comma or period? Both are valid The sign to separate decimals when expressing a number in digits can be a period or a comma. In Mexico and the Caribbean a period is more commonly used, while a comma is mostly used in Spain. The book La ortografía de la lengua española advises unification so it suggests using a period (once y medio: 11.5), but it also notes than when a comma is used, it shouldn’t be considered a mistake (once y medio: 11,5). http://www.fundeu.es

How to call “b” and “v” The Real Academia de la Lengua (RAE) recommends that Spanish letters have only one name, so “b” should be “be” and “v” should be “uve”. But that doesn’t mean the other names used for these two letters are incorrect. The letter “v” has two names: “uve” (mostly used in Spain), and “ve” (mostly used in America). The name “ve” usually goes along with the adjectives “corta, chica, chiquita, pequeña or baja” so it can be differentiated from the letter “b”. T
