swift types

how do you write out firstValue = 2 and secondValue = 4 to times to 8 in string interpolation ?

types.swift 
// Enter your code below
let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue 
let output = "\(product)

Let me give you a more detailed reply. See below code.

let firstValue = 2
let secondValue = 4
let result = firstValue * secondValue

print("the result of your multiplication is \(result)")

first 3 lines is the calculation. What I additionally did in the last line is to print the result variable. When you have worked with XCode before, you know that this print("...") is used to write the text in brackets into the console. The last line also contains the string interpolation. By using... 

\(VariableGoesHere)

...I can simply insert the value stored in a variable into the string.

Does this make any sense to you? :)

You need to add " after (product) in order to finish the string statement

let firstValue = 2 let secondValue = 4 let product = firstValue * secondValue let output = "(product)" says format of your output doesnt match requirments ? How do i compute the product and print out the product in a formatted string?The string should read: "The product of 2 times 4 is 8".
