Write a function, add that takes two numbers and returns their sum.
Write a function, average that takes three numbers and returns their average.
Restriction: You cannot use + inside this function's body
Write the above formula (pythagorean theorem) in python, representing it as a function.
Write a function pythagorean_theorem, which takes two numbers, a and b, and returns c.
Write a function, hypotenuse_times_3, that takes a and b as arguments,
it finds c using pythagorean_theorem, and returns the result of c * 3

A taxi charges:
- $4 for the first km
- $2 for each km from 2 to 10
- $1.50 for each km beyond 10
Write a function that takes the number of kilometers traveled and returns the total fare. Example:
>>> taxi_meter(1)
4
>>> taxi_meter(2)
6
>>> taxi_meter(10)
22
>>> taxi_meter(15)

Write a function that takes two positive integers, n and m, and returns sum of all numbers
between 1 and n that are fully divisible by m. Example:
>>> sum_of_divisibles(6, 3)
9
>>> sum_of_divisibles(10, 4)
