# Variable and String and Number Interpolation

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.

types.swift
```// Enter your code below
let firstValue = 2
let secondValue = 4

let product = firstValue * secondValue
let output = "The product of" + firstValue + "times" + secondValue + "is" +  product
```

```let output = "The product of \(firstValue) times \(secondValue) is \(product)"
