# Functions are typically designated by the function name and parentheses, with an argument in the parentheses 
println("println is a function and this is the argument")

# If there is no input, a blank line is printed
println()

# Operators are exceptions to the parentheses rule
a = 12 + 14
println(a)

# Creating a basic function
function add_numbers(x, y)
    x + y
    end

# Using the function
println(add_numbers(1, 2))
println(add_numbers(2, 3))
println(add_numbers(3, 4))
