What am i doing wrong?

I can't seem to find the problem?

// Enter your code below
let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
let output = "\("The product of "), \(firstValue), \(" times "), \(secondValue), \(" is "), \(product)"

When using string interpolation you only use \() for the variables you want to insert in the string, all of the actual text that should be in the string should just be typed like normal, without any special formatting. Like this:

let output = "The product of \(firstValue) times \(secondValue) is \(product)"

That's part of what makes string interpolation so useful. You can write a normal string and just place the contents of variables within it, without having to add a bunch of extra quote marks of anything like that.
