I am unsure how to complete Step 2. I have tried: let output = "\(firstValue) * \(secondValue)

Unsure how to put the interpolated string together for this question

// Enter your code below

let firstValue = 2
let secondValue = 4

let product = firstValue * secondValue 

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

You also need to add the text to the calculation like: The product of 2 times 4 is 8" let output = "The product of \(firstValue) times \(secondValue) is \(product)"

I also just started the track, sometimes reading the assigment again helps :)

You forgot to put a closing quotation mark!

Try this instead of let output = "(firstValue) * (secondValue):

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

Good luck!

I hope this helps, Alex

Thanks Alex! But I still get an error The format of your output string doesn't match the requirements listed. Double check the example given in the directions!

Here is the whole exercise:

Given these two values we just declared, we want to compute the product and print out the product in a formatted string.

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.

let firstValue = 2 let secondValue = 4

let product = firstValue * secondValue

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