I'm a bit stuck with step two. Where am I going wrong?
Challenge Task 2 of 2
Using these values, 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: Int = 20 let secondValue: Int = 40 let product = "\(firstValue * secondValue)" let output: String = "the product of 20 x 40 is" + product

Hi William -
The first error is you do not need to use string interpolation to multiply your two value The second error is you need to use string interpolation for output
let firstValue = 20 let secondValue = 40 let product = firstValue * secondValue let output = "The product of \(firstValue) times \(secondValue) is \(product)"
