A function with parameters has a couple of requirements:

• The function call must include the same number of arguments as there are parameters.
• The corresponding arguments must be passed in the same order.

By calling a function with arguments, you are telling a function, “Hey function, when you execute, use these values where you have parameters in your definition.”

While it executes, anywhere the function comes across a parameter, it replaces the parameter with the corresponding argument you gave it.
