I have no idea why this answer is not working, I've tried the equation in playground and it works correctly.
// Enter your code below
func getRemainder(value: Int, divisor: Int) -> Int {
let getRemainderSum = value % divisor
return getRemainderSum
}

return a % b

585 PointsDon't worry, figured it out :)
func getRemainder(value a: Int, divisor b: Int) -> Int { return a % b }

585 PointsHi Magnus,
Thanks for the quick reply. Would you please be able to write out the entire correct function as I seem to try this and it's still not working. I want to figure out where I am going wrong.
Thanks,
Chris
