## General
|
||
|
|
|
||
|
|
- An integer literal can be defined as one or more consecutive digits.
|
||
|
|
|
||
|
|
## 1. Define the expected oven time in minutes
|
||
|
|
|
||
|
|
- You need to define a [function][functions] without any parameters.
|
||
|
|
|
||
|
|
## 2. Calculate the remaining oven time in minutes
|
||
|
|
|
||
|
|
- You need to define a [function][functions] with a single parameter.
|
||
|
|
- You can use and refer to the previously defined item by its name.
|
||
|
|
- The last expression in a function is [automatically returned][return-values] from the function; you don't have to explicitly indicate which value to return.
|
||
|
|
- You can use the [mathematical operator for subtraction][operators] to subtract values.
|
||
|
|
|
||
|
|
## 3. Calculate the preparation time in minutes
|
||
|
|
|
||
|
|
- You need to define a [function][functions] with a single parameter.
|
||
|
|
- You can use the [mathematical operator for multiplicaton][operators] to multiply values.
|
||
|
|
|
||
|
|
## 4. Calculate the elapsed time in minutes
|
||
|
|
|
||
|
|
- You need to define a [function][functions] with two parameters.
|
||
|
|
- You can [call][functions] one of the other functions you've defined previously.
|
||
|
|
- You can use the [mathematical operator for addition][operators] to add values.
