What is the difference between constants and variables?

In simple words, a variable is a value that is changing or that has the ability to change. A constant is a value that remains unchanged.

The key difference between constants and variables is that constants are fixed values and variables are varying values in an algebraic expression. 

Example: In x + z = 8, x and z are variables and 8 is a constant
