People In ancient india used names of colors to represent unknown values.
The mathematician David Hilbert used names of colors, such as "white" and "black," to represent unknown values in his work in mathematics and logic. This approach was part of his concept of "Game Semantics" where colors were used to represent players and moves in mathematical games, allowing for the study of logical systems.
People from Ancient India.
They are used to represent known and unknown values in equations. Usually x, y, and z are unknown; and a, b, and c are known. But u can use anything to represent anything! It helps to solve for unknowns that you need to figure out!
The choice of a token to represent an unknown is wide open. Commonly, x and y are used, but one may use any letter of the alphabet, particularly if it has some phonic association. c is often used as a token for the speed of light; as a substitute for the word celerity.
The letters b and c could represent almost any number. They are used in equations normally because they are unknown, and so that we can figure out their values through solving the problem.
