# HIGHER-ORDER FUNCTIONS with two parameters

higher-order functions

**Here is what the above code is Doing:**

1. We’re defining a function called “apply_to_one” that takes in a function and a number.

2. We’re defining a function called “add_one” that takes in a number and returns that number plus one.

3. We’re defining a function called “subtract_one” that takes in a number and returns that number minus one.

4. We’re calling the “apply_to_one” function with the “add_one” function and the number 1.

5. We’re calling the “apply_to_one” function with the “subtract_one” function and the number 1.
