how do i get help with step 2

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.

how do i complete this? I don't understand what to do and i have watched video 4 times. The description of what to do i am not getting please help

// Enter your code below
let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
let output = "\("The product of"), \(firstValue) * \(secondValue) = \(product)"

Hey Matt! You're so stinking close. First, kill the backslash, parentheses and and quotes directly around the 'The product of'; it's not needed. The interpolation with the () (backslash and parens) will calculate the value placed within it.


let name = "Justin"
let message = "Hello \(name)"
//"Hello Justin"

Now the compiler in Treehouse is expecting what it's asking for. So make sure your output prints exactly "The product of 2 times 4 is 8". Which yours does not. Yours is using the times operator for the literal word 'times' and the equal sign for 'is'.

If you want the answer, it is as follows:

let output = "The product of \(firstValue) times \(secondValue) is \(product)"
//The product of 2 times 4 is 8

Again. You were so close. Good job though! Feel free to reach out in the future.

Its funny I ended up figuring it out but thanks so much for your reply :)
