Question is saying that my string literal being assigned to output but be an interpolated string.

let firstValue = 2 let secondValue = 4

let product = firstValue * secondValue

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

types.swift 
// Enter your code below
let firstValue = 2
let secondValue = 4

let product = firstValue * secondValue 


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

Hello,

To give a String value to the output constant, you should use the syntax:

"The product of x times y is z". Since you want to call the data stored on first and second value, the way to do it is like this:

"The product of (firstValue) times (secondValue) is (product)"

As you can see, the special character () call the data stored in the constants rather than writing the names of the constants (firsValue or secondValue)

Jus want to add, that for some reason the back slash was removed from my previous post. The syntax for the constants within the " " should be:

backSlash()

Hope you can understand what I mean

I found a way to write code within the post, let's see if it works. The correct syntax should be:

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

Notice I only used the back slash followed by parentheses only when I want to view the data stored in the constants
