Interpolation: Lesson 2 Quiz 2 question 2. Putting firstValue and secondValue as the product. Please help me...

The question directions state that that the string should say, "The product of 2 and 4 is 8." But when i put in the integers i used, it says it is wrong. I have tried every possible option I can think of, but to no avail...

types.swift 
// Enter your code below
let firstValue = 10
let secondValue = 5
let product = 10 * 5
let output = "The product of firstValue times secondValue is 50"

for your product constant, you need to be multiplying the first and second values, but youve hard coded them in as 5 and 10.

and in your output statement, dont forget to use interpolation for the product as well, rather than hard coding in 50.

Dont forget to use the correct interpolation syntax as well. Simply saying firstValue wont retrieve the correct value. The syntax is 

let constant = "whatever"
let randomStatement = "This displays \(constant)."
