in ruby is there a distinction between a method and function

Ruby functions vs methods

Im just reading some ruby documentation and t seems to use the term function and method in an interchangeable way, i jut wanted to know if there is any distinction?

the docs im looking at refer to this as a function:

def saysomething()
  puts "Hello"
end

saysomething

and this a method:

def multiply(val1, val2 )
  result = val1 * val2
  puts result
end

this may be a something semantic but i wanted to check
