-// In this exercise, you will need to work out what num represents?

-// It will help to think about the order in which expressions are evaluated
-// Try logging the value of num and running the program several times to build an idea of what the program is doing
+console.log(num);
+// what does num represent?
+// num represents a random whole number (integer) between minimum (1) and maximum (100) inclusive.
+
+//Breakdown of the expression:
+// 1. Math.random() generates a decimal number from 0 (inclusive) up to, but not including, 1.
+// 2. (maximum - minimum + 1) calculates the range size (100 - 1 + 1 = 100).
+// 3. Math.random() * 100 scales the random decimal to a range between 0 and 99.999...
+// 4. Math.floor() rounds that value down to the nearest whole integer (0 to 99).
+// 5. + minimum (+ 1) shifts the final value up into the target range of 1 to 100.
