I need help with that.

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.

types.swift
// Enter your code below
let firstValue = 5
let secondValue = 10
let product = firstValue * secondValue

Hi There,

let description: String = "The product of multiplying \(firstValue) by \(secondValue) is \(product)"

Now let me explain: In the previous challenges you did great, you have stored a random integer inside 2 constants with the names firstValue and SecondValue and their product in a constant named product

In this challenge you are asked to create a description of the operation and a template is given to you : " The product of multiplying firstValue by secondValue is product. "

In the answer above I'm assigning the description constant of type String and i've explicitly written it but you don't have to. Then written the same as I've demonstrated a few lines ago.

Note - String Interpolation a.k.a () substitues whatever value is between the parenthesis with a string version of it

Hope this helps

Shay
