Here thus in the history of equations the first letters of the alphabet became indicatively known as coefficients, while the last letters as unknown terms (an incerti ordinis). In algebraic geometry, again, a similar rule was to be observed: the last letters of the alphabet came to denote the variable or current coordinates.
Thomas Harriot in a posthumous publication is the first to use symbols < and > to indicate "less than" and "greater than", respectively. [26] 1637: Pierre de Fermat claims to have proven Fermat's Last Theorem in his copy of Diophantus' Arithmetica, 1637: René Descartes introduces the use of the letters z, y, and x for unknown quantities. [27 ...
Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
High-Rise Pantograph – The new-design world record pantograph, developed completely in-house for use in DFC & other freight routes with height of 7.5 metres (25 ft). [ 304 ] Commercial CCU plant: Tuticorin Alkali Chemicals and Fertilizers Limited (TFL) partnered with Carbon Clean to create the world's first fully commercial CCU plant.
A linear Diophantine equation is an equation of the form ax + by = c where x and y are unknown quantities and a, b, and c are known quantities with integer values. The algorithm was originally invented by the Indian astronomer-mathematician Āryabhaṭa (476–550 CE) and is described very briefly in his Āryabhaṭīya .

Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
