String Interpolation

I am triying to return the remainder of two arguments inside a sentence but am getting the error "Make sure you return a nicely formatted string." Please help

method.rb 
def mod(a, b)   
  c = a % b
  puts "The remainder of #{a} divided by #{b} is #{c}."
  return c  
end

mod(7, 2)

Hiya Andrew,

The question wants you to return the formatted string, not output it. So, change puts to return or just leave the string as the last line in the method;

def mod(a, b)   
  c = a % b
  return "The remainder of #{a} divided by #{b} is #{c}."
end

or this - Ruby returns the value of the last line of the method if there's no specific return command: 

def mod(a, b)   
  c = a % b
  "The remainder of #{a} divided by #{b} is #{c}."
end
