# per your example
def add(a, b):
  return float(a) + float(b)

This might throw an error, so you'll need to wrap that a Try/Except block

def add(a,b):
  try:
    return float(a) + float(b)
  except ValueError:
    return None

Samuel's response worked perfectly. Don't forget proper indentation, they won't let your code pass without it!
