 // =============> explain this error message here
+// SyntaxError: This means there is something wrong with the way the code is written, so JavaScript cannot understand it.
+// unexpected number: This means that the code is trying to use a number where it expects an identifier (like a variable name). In this case, the function parameter is incorrectly named as a number (3) instead of a valid identifier.
 
 // Finally, correct the code to fix the problem
+// to fix the problem, we need to change the parameter name to a valid identifier, like "num" or "number".
