 // Predict and explain first...
 //  =============> write your prediction here
+// Answer: I predict that what happens is `The sum of 10 and 32 is undefined` gets logged to the console.
+// That is because even though the function sum has a return statement, it doesn't return anything. There
+// is a value that is meant to be returned below the return statement, but because the function already returned
+// it will never reach that line in execution. That is why it is greyed out.
 
+/*
 function sum(a, b) {
   return;
   a + b;
 }
 
 console.log(`The sum of 10 and 32 is ${sum(10, 32)}`);
+*/
 
 // =============> write your explanation here
+// Answer: Running the code logged "The sum of 10 and 32 is undefined" like I thought. I will fix the problem
+// by moving a + b; in the function body to be on the same line as return, so it gets returned instead of undefined.
+
 // Finally, correct the code to fix the problem
 //  =============> write your new code here
+
+function sum(a, b) {
+  return a + b;
+}
+
+console.log(`The sum of 10 and 32 is ${sum(10, 32)}`);
+
+// Answer: now "The sum of 10 and 32 is 42" is logged.
