13.Practice writing functions
In the Writing functions video, we learned:

Don't abbreviate variable names because it can get confusing after time has passed
Write some functions of your own:
Take somebody's name and say a greeting to them;
Write a function to subtract two numbers;
Now one to multiply two numbers. Then create a new function called threeTimes to
multiply three numbers together.
Now write one to divide two numbers. Then write a new function called remainder to
find the remainder of two numbers.
Prompt the user to enter their age, another to enter their name and another to enter
their favorite food. Then return an alert with a sentence that combines all of this
information.
Write a function that calculates BMI using two arguments. Then write another function
that prompts the user for their height and weight, uses the BMI function and alerts the
user of their BMI.
