# Hints ## General - An [integer value][integers] can be defined as one or more consecutive digits. - [String][string] literals are a sequence of characters surrounded by double quotes. ## 1. Define the expected oven time in minutes - You need to define a [function][functions] without any arguments. - You need to return an [integer][integers]. ## 2. Calculate the remaining oven time in minutes - You need to define a [function][functions] with a single argument. - You have to [implicitly return an integer][return] from a function. - The function's argument is an [integer][integers]. - 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 argument. - You have to [implicitly return an integer][return] from a function. - The function's argument is an [integer][integers]. - You can use the [mathematical operator for multiplication][operators] to multiply values. ## 4. Calculate the total working time in minutes - You need to define a [function][functions] with two arguments. - You have to [implicitly return an integer][return] from a function. - The function's argument is an [integer][integers]. - You can invoke one of the other functions you've defined previously. - You can use the [mathematical operator for addition][operators] to add values. ## 5. Create a notification that the lasagna is ready - You need to define a [function][functions] without any arguments. - You need to return a [string][string].
