Create a method called "add" that steals two arguments and returns the sum off two numbers.

MYSELF typed below and it does't work. I created 2 arguments also give it a sum.

method.rb 
def add(a, b)
  puts a + b
end

puts add(2, 3)

You don't have to getting doubly puts statements, it should have by return or no return to sum up automatically. ;)

Example:

def add(a, b)
  return a + b
end

puts add(2, 3)

returned is at return the valuables of of last comment being done inbound the method in order to get the valuable you placement numbers(2, 3) outside definition method (def add), however, puts statements is like for displaying the message you type inside definition method but haven't received numbers outdoors.
