 // =============> write your explanation here
 // Answer below:
-// The code has two function parameters, it prints the parameters without an actual value. To correct this code the console.log has to be replaced with retun 
-// To return the value of the parameters when called
+// The original logs the product instead of returning it, so the function call inside the template string gives undefined

 // Answer below:
 
 // The global constant variable outside the function has affected the code and caused it to always reference the last number of the global variable
-// To fix this, the global variable will be removed from code and the function getLastDigit should take the variable name "num" assigned to the global variable.
+// To fix this, getLastDigit needed its own parameter, so num comes from whatever you pass in
