+// The code will print "The result of multiplying 10 and 32 is undefined"
+// for the result because the function multiply does not return any
+// value, it only uses console.log to print the result of the 
+// multiplication instead of return. Therefore when we try to use
+// the result of the function in the template literal, it will be
+// undefined as it logs the value but returns nothing.

 // =============> write your explanation here
+// console.log() inside a function will print the result to the console
+// but it does not return any value. When we try to use the result
+// of the function in a template literal, it will be undefined
+// because the function does not return anything. To use a function's
+// results inside a template literal, the function must return
+// a value instead of just logging it to the console.
 
 // Finally, correct the code to fix the problem
