What about that math equation doesn't follow the directions? C= F*9/5+32.

// Enter your code below

func temperatureInFahrenheit(temperature: Double) -> Double{
((temperature * 9)/5)+32
return temperature

1 Answer

Close, but you can't use the local parameter that way.

func temperatureInFahrenheit(temperature: Double) -> Double {
  return temperature * 9 / 5 + 32

You can return the formula's result, as I do here. Or you can create a temp variable, assign it the formula's value, and then return that:

func temperatureInFahrenheit(temperature: Double) -> Double {
  let fahrenheit = temperature * 9 / 5 + 32
  return fahrenheit
