Hi Haitham,

The answer is often in the question. The trick with these challenges is you have to complete them with text displayed as in the question. Try this:

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

Hey Haytham Alam,

No reason to be frustrated! Let me clear things up. The question is asking you to assign a string literal to the constant output. The string looks like this "The product of 2 times 4 is 8". In order to do this, we write out the string literal and then use string interpolation to access the values stored inside of our variables/constants and display them as Strings.

Take a look below:

// Enter your code below

let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue

/* This will plug in the values stored in firstValue, secondValue, and product
and display them as Strings */

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

Good Luck!
