can you help me to solve this steps ?

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.

when i check it say that the string doesn't match with the requirements listed,

i tried more combination but it seems that i can't see where i'm wrong

// Enter your code below
let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
let output: String = "\("The product of") \(firstValue) \(" times") \(secondValue) \("is") \(product)"

Your String interpolation is a bit off: here is the correct String

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

Notice how it is within a single set of double quotes? Then anytime you want to put a variable in you do not break the quotes but instead add:


and swift will replace that with the variables value
