i dont know what i have to do

types.swift
```// Enter your code below

let firstValue: Int=3
let secondValue: Int=5

let product: Int = firstValue*secondValue
let
```

String interpolation is "like this but adding () within the string to input a value"

so...

```// Enter your code below
let firstValue: Int = 1
let secondValue: Int = 2

let product: Int = firstValue * secondValue
let output: String = "The product of \(firstValue) times \(secondValue) is \(product)"
```

would return "The product of 1 times 2 is 2

i dint understand the last sentence could you explain it thank you

Yes, so basically in Swift and most other languages, if you see "" it means that anything within the "" is a string. No matter what is in the "" it will be registered as a string according to the language. The exception is if you put () inside the "". So for example

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

What the program is ACTUALLY seeing is "The product of 1 times 2 is 2" because those are the values inside of (). DOes that make sense?

So what it would be the answer, I been trying but its not working the senteces and also I tried to make like this let output = (firstValue) * (secondValue) = (product)" but it didn't work as well.

I actually did it, thank you sir
