This looks right, but it's telling me that I'm wrong, even though the preview tells me there is nothing wrong with it. Help please?

types.swift 
// Enter your code below

let firstValue: Int = 2
let secondValue: Int = 4

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

Hey there,

good job, you almost got it right! The problem is that you're setting the product constant to the String "firstValue * secondValue". To multiply the values you have to remove the quotes around the calculation like so:

// Enter your code below

let firstValue: Int = 2
let secondValue: Int = 4

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

I hope that helps! :)

you are putting let product constant value inside quotes " ". so product constant is becoming a String.

let product = firstValue * secondValue

this way it will stay as an Integer
