# Hints

## General

- Make use of anonymous functions.
- Anonymous functions can reference variables in scope when they were defined.

## 1. Create an adder

- Return an anonymous function which adds the argument from the anonymous function to the argument passed in to `secret_add`.

## 2. Create a subtractor

- Return an anonymous function which subtracts the argument passed in to `secret_subtract` from the argument from the anonymous function.

## 3. Create a multiplier

- Return an anonymous function which multiplies the argument from the anonymous function to the argument passed in to `secret_multiply`.

## 4. Create a divider

- Return an anonymous function which divides the argument from the anonymous function by the argument passed in to `secret_divide`.

## 5. Create a function combiner

- Return an anonymous function which each of the functions passed in to `secret_combine`.
