using string interpolation, create string literal... -____-

Step 1: Declare a constant named product and assign the result of multiplying firstValue and secondValue together. (To multiply two values, a and b, we write a * b).

Step 2: Using string interpolation, create a string literal that describes the operation we just performed. For example, given the following values for firstValue, secondValue and product respectively: 2, 4, 8. The string should read: "The product of 2 times 4 is 8". Assign this string to a constant named output.

/////////////////////where am i screwing up?////////////

types.swift 
// Enter your code below
let firstValue = 2
let secondValue = 4 
let product = firstValue * secondValue
let output = "\(product) \(8)"

Hello Quentin!, you have the code almost right. Just be more careful in the second part it should ridden, for example:

let firstValue = 2 let secondValue = 4 let product = firstValue * secondValue

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

The string should read: "The product of 2 times 4 is 8."

However, your output is "8 8".

So, try formatting your output string again, this time using the right words and numbers.
