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
```

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)"
```
