I don't understand how to complete the second step of the question. It's asking to use an interpolated which would allow me to say the product of 20 times 30 is 600. Someone please respond. Thank you.

Hi Maged,

To perform string interpolation, you want to put your variable or constant name in parentheses (the parentheses will hold what is to be interpolated), and have a backslash before it to tell the compiler that you are using interpolation. All of this is written within the string (which is a nice feature of interpolation: you do not need to write any part of the value outside of your quotation marks.)

// Enter your code below
let firstValue: Int = 5
let secondValue: Int = 7

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

Hope this helps!
