Courses Plus Student 26,868 PointsHi Nisa. Looks like you're having trouble with part 2 of 2 in this code challenge. Let me break it down for you.
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).
This 1st step is easy.
let product = firstValue * secondValue // multiply 2 constants to get its product
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.
The description is lengthy, but the key here is this example String "The product of 2 times 4 is 8". All you need to do is replace 2, 4, and 8 from this String with firstValue, secondValue, product using String interpolation, respectively; and don't forget to assign the String to a new constant named output
The final code should look sth like the following.
// Enter your code below
let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue // multiply 2 constants to get its product
let output = "The product of \(firstValue) times \(secondValue) is \(product)"
Hope it helps.

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.
let firstValue = 248
let secondValue = 428
let product = firstValue * secondValue // multiply 2 constants to get its product
let output = "The product of \(firstValue) times \(secondValue) is \(product)"

For this challenge, let's pretend we're building a calculator that outputs a string with the result of a math operation.
Start by declaring two constants, firstValue and secondValue and to both of them assign some integer values. (Try and keep the values within a sensible range. Extremely high values will time out the challenge editor).
let firstValue = 248
let secondValue = 428
let product = firstValue * secondValue // multiply 2 constants to get its product
