Create a method called "add" that takes two arguments and returns the sum of two numbers.

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

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

puts add(2, 3)

You don't have to use twice puts statements, it should have either return or without return to sum up automatically. ;)

Example:

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

puts add(2, 3)

OK, I got it. maybe a dumb question. What does 'return' do?

return is to return the values of the last statement being executed in the method in order to get the values you put numbers(2, 3) outside definition method (def add), however, puts statements is like only displaying the message you type inside definition method but haven't received numbers outside.
