Hi, what is it im doing wrong? ;(

let firstValue = 2000 let secondValue = 3000

let product = "(firstValue) * (secondValue)"

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

types.swift 
let firstValue = 2
let secondValue = 3

let product = "\(firstValue) * \(secondValue)"

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

First, the product constant needs to just store the product of the two Integers, and as such shouldn't store a string. Second, you seem to have used both string interpolation as well as concatenation in attempt to create the output constant that needs to store a string that will print "The product of 2 times 3 is 6". Instead what you have done is created a string that would output "The product of (firstValue) times (secondValue) is (product)".

let firstValue = 2
let secondValue = 3

let product = firstValue * secondValue

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

No need to put firstValue and secondValue in string interpolation when multiplying.
