Having trouble with "Create a method called "hello" that takes one argument." in Ruby

I am having trouble with my code on "Create a method called "hello" that takes one argument." in the Ruby Challenge Task 1 of 1. What is wrong with my code?

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

add(4, 5)

Your function takes two arguments - a and b. To change it to a hello() function that greets someone, it should look more like this:

def hello(name)
  puts "Hello " + name
end

You also are calling a different function add() that takes two arguments. Instead, you should be calling hello(), passing a single argument, e.g.:

hello("Mark")

Hi Mark,

I think your method has two arguments. and you did not define 'add' method before using 'add' method.

def hello msg
  puts msg
end

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