# 
## 1. Define expected bake time in minutes

- You need to [name][naming] a [constant][constants], and [assign][assignment] it an [integer][numbers] value.
  This constant should be the first thing after the docstring that is at the top of the file.
  Remember to remove the #TODO comment after defining the constant.

## 2. Calculate remaining bake time in minutes

- You need to define a [function][defining functions] with a single parameter representing the time elapsed so far.
- Use the [mathematical operator for subtraction][numbers] to subtract values.
- This function should [return a value][return].

## 3. Calculate preparation time in minutes

- You need to define a [function][defining functions] with a single parameter representing the number of layers.
- Use the [mathematical operator for multiplication][numbers] to multiply values.
- You could define an extra _constant_ for the time in minutes per layer rather than using a "magic number" in your code.
- This function should [return a value][return].

## 4. Calculate total elapsed cooking time (prep + bake) in minutes

- You need to define a [function][defining functions] with two parameters.
- Remember: you can always _call_ a function you've defined previously.
- You can use the [mathematical operator for addition][python as a calculator] to sum values.
- This function should [return a value][return].
