HI Maged,

I'm not sure what you are asking here?

The brackets used in this question are for string interpolation. This allows you to add the contents of a variable (or constant) into a string. The quiz here uses this when creating the output string like this: 

let firstValue = 10
let secondValue = 20
let product = firstValue * secondValue
let output = "The product of \(firstValue) times \(secondValue) is \(product)"

In place of \(firstValue), the string will contain the value of firstValue which is 10 in this case. The same with the other two constant names.

I hope that helps - if not, let me know what it is that's confusing you and I'll get back to you.

Steve.
