 // Predict and explain first...
 
 // =============> write your prediction here
+// Answer: I predict the console will log first 320, and then on a new line "The result of multiplying 10 and 32 is ${NaN}"
+// This is because the function logs the result in it's body, so it will log it first as it is run, but
+// because it's not explicitly returning anything, it will just return NaN into the string literal logged at the end.
 
+/*
 function multiply(a, b) {
   console.log(a * b);
 }
 
 console.log(`The result of multiplying 10 and 32 is ${multiply(10, 32)}`);
+*/
 
 // =============> write your explanation here
+// Answer: In reality, I was almost correct, but the function returned undefined, not NaN, so it logged
+// 320, and then The result of multiplying 10 and 32 is undefined. Oh and also of course the string
+// interpolation brackets weren't included in the logged string like I had predicted.
+// I will fix the problem by returning a * b in the function body, instead of logging it.
 
 // Finally, correct the code to fix the problem
 //  =============> write your new code here

+function multiply(a, b) {
