What is not good in here?

I don't get it, what is not good in here?

// Enter your code below

let firstValue: Int = 100
let secondValue: Int = 50

let answer: Int = firstValue + secondValue

let product = "\(firstValue * secondValue)"

let output = "The product of 100 times 50 is \(product)"

Hi Lucas,

Firstly, for this challenge I think your answer constant is redundant , as I don't recall the challenge to ask for it.

Secondly, looking over the string interpolation's definition might be of help. I've fetched it for you:

String interpolation is a way to construct a new String value from a mix of constants, variables, literals, and expressions by including their values inside a string literal.

Thirdly, in the output constant, you aren't asked to hard code the values , but to construct your constant making use of string interpolation and your constants.

Finally, if you've read all of the above and still feel a bit confused, I'll provide an example below. However, I do hope you've had another go at it yourself before simply copying.

let firstValue = 10
let secondValue = 6

let product = firstValue * secondValue

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