What to do now

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.

// Enter your code below
let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
let output = "The product of " + firstValue + "times" + secondValue + "is" + product

You are asked to use String Interpolation, not concatenation. What you are doing by "adding" strings to the values to create one large string, is known as String Concatenation.

You want to interpolate, meaning insert them into a single string. like:

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

Whoops, forgot you need to put a backslash in front of each interpolated value but the comment poster keeps deleting my backslashes.
