In mathematics, a fixed quantity or one that does not change its value in relation to variables is called a constant . For example, in the algebraic expression y ^ 2 = 5 ^ x - 3, the numbers 3 and 5 are constants. In physics, certain quantities are regarded as universal constants, such as the speed of light in a vacuum. This section describes constants that the Expression Calculator has built in.
