A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants.
Constant is an entity whose value does not change throughout the calculation. It can be a number, decimal, or a fraction. A constant in math is often represented by a letter or a symbol or a number. Examples of constants: 2, 1.5, $\sqrt{2}, \frac{3}{4}$
List of mathematical constants. A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]

The constants are generally numbers, but may be any expression that do not involve the indeterminates, and represent mathematical objects that can be added and multiplied.
A constant has multiple different meanings in mathematics depending on the context. In its simplest definition, a constant is a fixed value, such as the number 5. It does not change with respect to the variables in an expression or equation .
