i dont understand what they are asking me in the second step/

the first step i did, but i dont understand how they want for me to write the second step.

// Enter your code below

let firstValue = 10
let secondValue = 30

let product = firstValue * secondValue

let output = "\(firstValue) * \(secondValue)"

This worked: // Enter your code below let firstValue = 11 let secondValue = 99 let output = "product = (firstValue*secondValue)"

Mr. Kujawski: I think (firstValue) and (secondValue) are Strings. So you are trying to multiply two Strings together which is illegal.

Hey Gil,

The issue is in your declaration for the constant output. Step 2 mentions the string that describes the operation should read: "The product of 10 times 30 is 300".

However, your current string for output is not using the product constant, and it reads: "10 * 30".

To complete this step, try to assign the correct string to the constant output:

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

Hope this helps!

let output = "\(firstValue)*\(secondValue)" \\ "10*30"
let output ="\(firstValue*secondValue)" \\ "300"
