Definition
A constant is a value that does not change and is not multiplied by a variable. It's a fixed number within an expression or equation.
For example:
In the expression 3x + 7, the number 7 is the constant because it remains the same regardless of the value of x.
In the equation 2x - 5 = 9, the number -5 and the number 9 are constants.
Constants provide the fixed part of an expression or equation, while variables can change and take on different values.
