Difficulties with step 2 of question 2. Could someone elaborate, so I know what I'm doing wrong or misunderstanding, TY!

Using string interpolation, create a string literal that describes the operation we just performed. For example, fiven 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.

types.swift 
// Enter your code below

let firstValue = 7

let secondValue = 10

let product = firstValue * secondValue

let output = "The product of" firstalue * secondValue

From the Swift documentation on Apple's Developer site:

"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."

There is a special syntax you use to include constants and variables inside strings. For example:

let age = 20
let sentence = "The man is \(age) years old."

In that snippet, \(age) is replaced with the value of the age constant.

Hope this helps!
