Error says cannot convert string to float

The question asks to use float() before adding, but I keep getting an error. Are my arguments supposed to be numbers?

def add(num1, num2):
  return(float(num1 + num2))

No they aren't. But the way you have the code now it adds the numbers then converts the sum to a float. You want to try to make them floats before you add them. See this code:

def add(num1, num2):
  return float(num1) + float(num2)
