Hi Sean you set up the function and parameters correctly the part that isn't letting you pass is the body of the statement. there isn't a return statement and you have separate lines for the calculation they want. It must be on a single line and written just like a math problem where you have the operations performed in the order they ask. So you need to return temperature and run the calculation. 

let example = ((temperature * 2) / 4 + 44)

hope this helps !

Looks like the issue is you aren't returning the temperature in that function:

// Enter your code below

func temperatureInFahrenheit(temperature: Double) -> Double {

    temperature *= 9.0
    temperature /= 5
    temperature + 32.0
    return temperature
  }
