# Exercise: ModulesAndFunctions-1
# Extend the Times module with a triple function that multiplies its parameter by three.

# Exercise: ModulesAndFunctions-2
# Run the result in IEx. Use both techniques to compile the file.

# Exercise: ModulesAndFunctions-3
# Add a quadruple function. (Maybe it could call the double function.…)
