Best Answer

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.

variable

You can represent values using variables. This can only be done with whole numbers.

an unwillingness to understand alternative points of view and to take the values they represent seriously

Variables. If you're talking about math.....

In every formula, there are numbers and unknown values. What has to be done is to perform the calculation by removing the known value and leaving the unknown. For instance; x+3=5. In this case, one has two values that must be removed to discover the unknown value. So one has to perform the inversion of the formula to solve for the unknown quantity. Therefore, we "flip" the equation. Since X is the unknown, we must use what we have. Therefore we subtract (doing the inverse of the stated equation) 3 from the total of 5. The sum of the answer will give the unknown quantity, in this case 2. To prove that you are right, you "plug in" the value that you have solved for into the missing value space and perform the equation to see if the answer is correct.

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.

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!

In algebra, x can have any value as the letter is used to represent any number that is unknown until solved. e.g. 2x=4 x=2 In Roman Numerals, X is 10.

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.

If you mean a variable then it is an unknown quantity that can represent many values until its specific value is determined usually by solving an equation.
