# let firstValue = 1234 let secondValue = 1234 let product = firstValue + secondValue let output = " The product of

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.

let firstValue = 1 let secondValue = 3

let product = result a * b let a = 2 let b = 4

Bummer make sure the string literal you creating is assigned to a constante called output? Why?

MY CODE:

let firstValue = 1234 let secondValue = 1234 let product = firstValue + secondValue let output = " The product of (firstValue), times(secondValue),is (product)."

types.swift
```// Enter your code below
let firstValue = 1234
let secondValue = 1234
let product = firstValue + secondValue
let output = " The product of \(firstValue), times\(secondValue),is \(product)."
```

An error keep poping up can someone help me did I miss anything?

Nearly, yes - remove the commas - take out these , , so the string looks like:

```let output = "The product of \(firstValue) times \(secondValue) is \(product)." // CORRECT
let output = "The product of \(firstValue), times \(secondValue),is \(product)." // incorrect - remove , ,
```

HI there,

Have a look at my code in my last answer, a product is the result of multiplying two numbers together so use `*` rather than `+`. Like this:

```let product = firstValue * secondValue
```

Not:

```let product = firstValue + secondValue // incorrect; added together
```

Make sense?

Steve.

Yes, that is correct. You have included commas in your output string which are not needed.

The sting should look like this:

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

Not this, which you have:

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

No other characters are required so make sure you remove the commas and make sure your spacing is identical too. I have added a mark below each point that needs correcting either by amending the spaces or removing commas.

Steve.

Hi there,

You have added the two integers together; you want to multiply them? You want to take the commas out of the string too - the output isn't expecting to see them.

```let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
let output = "The product of \(firstValue) times \(secondValue) is \(product)"
```

Steve.

I dont get it can you show me an example?

how do I integers together?

Thank you for your help it stll has an error,

this what the error say

The format of your output string doesn't match the requirements listed. Double check the example given in the directions!

```let firstValue = 1234
let secondValue = 1234
let product = firstValue * secondValue
let output = "The product of \(firstValue), times \(secondValue),is \(product)."
```

An error

this is my code.

```let firstValue = 1234
let secondValue = 1234
let product = firstValue * secondValue
let output = "The product of \(firstValue), times \(secondValue),is \(product)."
```

Thank you a lot it works!!!
