# Product

It works in MyPlayground, but not the challenge Task. Wonder why?

Challenge Task 2 of 2

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 = 5
let secondValue = 9

let product (firstValue * secondValue)

let output (firstValue * secondValue = product)

"The product of \(firstValue) times \(secondValue) is \(product)."
```

Hey Matt Conway,

You're close but we have to fix a few things. You have to be using the assignment operator " = ". The assignment operator, = , assigns what is on the right side of it to the variable or constant on the left side of it.

```// Enter your code below
let firstValue = 5
let secondValue = 9

/* here you use the assignment operator to assign the result of
firstValue * secondValue to the constant named product */

let product = (firstValue * secondValue)

/* here you use the assignment operator again to assign the string literal
with the values of firstValue, secondValue, and product passed in
using string interpolation */

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

Good luck!
