CODE CHALLENGE: Create a method called "add" that takes two arguments and returns the sum of two numbers. -- Help pls.

hey all.. so this is from the Ruby Basics course and i'm stumped. my code matches what we did in the previous lesson, I've tried a few different things but for some reason it keeps returning: Check your Work error.

this is what i have: 

def add (a, b)
  puts "adding #{a} + #{b}: "
  return a+b
end

puts add (3, 3)
puts add (5, 5)

I've even tried: 

return add (3, 3)
return add (5, 5)

I've tried removing the puts statement in the method. to no avail..

all help is appreciated. answer not expected even just an explanation of where i am going wrong would help.

thanks!

You don't have to return it. Just print. 

puts ( " adding #{a} + #{b}:  ")
puts (a + b)

Return just returns the value and does not print to the screen. You need to print the answer so that it prints the answer to the screen. Hope this helps!

So I would want to use:

so then would

Puts return add (3, 3)

be what I'm looking for? Not sure why this is wracking my brain as hard as it is. Is my issue in the method its self of in the arguments below it?

In the lesson video it shows:

Puts add ( 3, 5)

Perhaps I'm just way over thinking this.
