what am i doing wrong?

Using these values, we want to compute the product and print out the product in a formatted string.

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.

// Enter your code below

let firstValue: Int = 6 let secondValue: Int = 5

let product = firstValue * secondValue

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

types.swift
// Enter your code below
let firstValue: Int = 2
let secondValue: Int = 4
let product = firstValue * secondValue // multiplying two values
let Output = "The product of \(firstValue) times \(secondValue) is \(product)"

In your markdown formatted code you have Output with an uppercase O. It should be lowercase.

There is no need to explicitly declare firstValue and secondValue as Ints, since we assign them values.

let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
let output = "The product of \(firstValue) times \(secondValue) is \(product)"
