I don't understand how you would write the firstValue and secondValue to multiply each other.

I'm having trouble figuring out how to end up with the final string.

types.swift 
// Enter your code below
let firstValue = 56
let secondValue = 34
let product = 
let output = "The product of"\(firstValue),"times"\(secondValue)"is"\(product)"

You never set the product constant to anything. It should be the firstValue multiplied by the secondValue 

// Enter your code below
let firstValue = 20;
let secondValue = 10;

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

For fun - a better way to do this in a project would be to set up a simple function that takes in two parameters and returns the product. This way you can reuse the function as many times as you want with different parameters. 

func multiply(firstValue, secondValue) {
return firstValue * secondValue
}

let product = multiply(20, 10)
