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 = 6 let secondValue: Int = 5

let product = firstValue * secondValue

let output: String = "The product of (firstValue) time (secondValue) is (product)"

types.swift
```// Enter your code below
let firstValue: Int = 2
let secondValue: Int = 4
let product = firstValue * secondValue // multiplying two values
let Output = "The product of \(firstValue) times \(secondValue) is \(product)"
```

```let firstValue = 2
