Hi there

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.

// Enter your code below
let firstValue = 1
let secondValue = 2

// part 2

let product = firstValue * secondValue  // step 1 
let output = "The product of \(firstValue) times \(secondValue) is \(product)" // step 2

Let me know if you have further question in regards to the answer.

String interpolation can be used like this:

let someInteger = 5
let someString = "\(someInteger)"

In the second part of the exercise you are asked to declare a third constant (product) and assign it the product of the first and second value. From there you have all the building blocks needed to create the output constant. Build the output string by using the technique above.
