In mathematics, a constant refers to a fixed value that dos not change throughout a particular equation or problem. It remains the same regardless of other variables or inputs.
For example, in the equation y=3x+5, the constant is 5 because it always stays the same, while the variable x and its coefficient 3 can vary. Constants are important in mathematical calculations, as they provide stability and serve as reference points for solving equations, graphing functions, and performing varios mathematical operations.
