Herbert Clark Hoover (August 10, 1874October 20, 1964) was an American engineer, businessman, and politician who served as the 31st President of the United States from 1929 to 1933 during the Great Depression.  A Republican, as Secretary of Commerce in the 1920s he introduced Progressive Era themes of efficiency in the business community and provided government support for standardization, efficiency and international trade.  As president from 1929 to 1933, his ambitious programs were overwhelmed by the Great Depression, which seemed to get worse every year despite the increasingly large-scale interventions he made in the economy.

"Mathematics" is a b-side single from Mos Def's solo debut album, "Black on Both Sides".  It contains lyrics about various social issues and asks the listener to add them up and come to conclusions about them.  Many references to numbers are found in this song and at times, Mos Def rhymes statistics in numerical order.  The song highlights the differences between the White and African-American citizens of the US and uses the lyrics "Do your math..." (from Erykah Badu's "On & On") telling young African-American's to 'do their maths' so they can avoid being part of the numerous degrading statistics he raps about in the opening and third verses of the song.  The song is produced by DJ Premier whose famous scratch samples make up the song's bridge.  Premier has called it one of his favorite beats. Collation is the assembly of written information into a standard order.  Many systems of collation are based on numerical order or alphabetical order, or extensions and combinations thereof.  Collation is a fundamental element of most office filing systems, library catalogs, and reference books. In computer science, a sorting algorithm is an algorithm that puts elements of a list in a certain order.  The most-used orders are numerical order and lexicographical order.  Efficient sorting is important for optimizing the use of other algorithms (such as search and merge algorithms) which require input data to be in sorted lists; it is also often useful for canonicalizing data and for producing human-readable output.  More formally, the output must satisfy two conditions: This is a complete list of routes in Jefferson County, West Virginia, United States.  Green: WV Secondary (County) Routes.
