Red (Taylor Swift album)
Red is the fourth studio album by American singer-songwriter Taylor Swift.
 It was released on October 22, 2012, by Big Machine Records, as the follow-up to her third studio album, "Speak Now".
 The album title was inspired by the "semi-toxic relationships" that Swift experienced during the process of conceiving this album, which Swift described the emotions she felt as "red emotions" due to their intense and tumultuous nature.
 "Red" touches on Swift's signature themes of love and heartbreak, however, from a more mature perspective while exploring other themes such as fame and the pressure of being in the limelight.
 The album features collaborations with producers and guest artists such as Gary Lightbody of Snow Patrol and Ed Sheeran and is noted for Swift's experimentation with new musical genres.
 Swift completed The Red Tour in support of the album on June 12, 2014, which became the highest-grossing tour of all time by a country artist, grossing over $150 million.

 In the 1650 BCE Rhind Mathematical Papyrus (RMP), the additive set of divisors were written in red ink.
 Red auxiliary numbers were used for several purposes The red auxiliary numbers were divisors of a greatest common divisor (GCD) that was used to convert fractions of the form 2/n to unit fraction series.
 The RMP 2/n table reported Egyptian fraction series by multiplying 2/n by a least common multiple (LCM) m, written as a unity (m/m), that obtained 2m/mn.
 Ahmes the RMP author, practiced the selection of red auxiliary numbers in RMP 21, 22, and 23 and detailed other aspects of the red number method in RMP 36.
 The scaled 2m/mn rational number was converted to a unit fraction series by finding the best set of divisors of (GCD) mn, as discussed below. Red Tour (EP)

 Because of the close relation between Red River system and Thái Bình river system, the two system are known as the common name "Red and Thai Binh rivers system".
