I don't understand..

It says what i have to do.. but i really don't understand it.

Step 2: Using string interpolation, create a string literal that describes the operation we just performed. For example, given the following values for firstValue, secondValue and product respectively: 2, 4, 8. The string should read: "The product of 2 times 4 is 8". Assign this string to a constant named output.

// Enter your code below
let firstValue: Int = 2001
let secondValue: Int = 2016

let product = firstValue * secondValue
let output =

Hi again! Remember what I said earlier about interpolation being the strange backslash and parentheses combo? That's what it's asking for now. Take a look at the line you're missing:

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

If you were to now print 'output' to the screen you'd get: "The product of 2001 times 2016 is 4034016"
