How do I format the constant that multiplies firstValue and secondValue and reveals the end product? Swift 3.0

I am working on a challenge so I can move on. The first task was to assign constants so I entered "let firstValue: Int = 10" and the second "let secondValue: Int = 50" and then the second task was to assign a constant named product that multiplied the values together so i entered "let product = firstValue*secondValue" but now the third task is to use string literal to interpolate the values and products together. "let output: String = "(firstValue) (secondValue) (product)" this is how i formatted it and it is wrong. I do not know how to format this task so that I can move on, can you help me?

types.swift 
// Enter your code below
let firstValue: Int = 10
let secondValue: Int = 50
let product = firstValue*secondValue
let output: String = "\(firstValue)*\(secondValue) = \(product)"

Hi Heather,

You have the right idea, but you need to incorporate literal string text alongside the interpolated values in order to generate the exact output the challenge wants.

Specifically:

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

David's answer is exactly right. For your reference, the final code challenge should be 

let firstValue: Int = 10
let secondValue: Int = 50
let product = firstValue * secondValue
let output = "The product of \(firstValue) times \(secondValue) is \(product)."
