assigning the value obtaining by multiplying firstValue and secondValue to product

What's wrong with my code?

let product = "firstValue * secondValue"

let firstValue = 2

let secondValue = 4

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

  1. You cannot calculate "Product" before defining and assigning values to "firstValue" and "secondValue".
  2. You should not use double quotes when calculating numbers
  3. You cannot include variables inside strings, must use concatenation

i think the corrections are as follows:

let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
let output = "The product of " + firstValue + " times " + secondValue + " is " product

hope this does it for ya

I see! Thank you so much Tareq for the answer!

in case anyone struggles with this, here is the right thing let firstValue = 2 let secondValue = 4 let product = firstValue * secondValue let output = "("The product of") (firstValue) ("times") (secondValue) ("is") (product)"
