 // num is a random whole number between minimum and maximum.
 // Math.random() returns a number that's greater than or equal to 0 and less than 1.
-/*Then we multiply by (maximum - minimum + 1) to get a range of possible values, which means 
-  all the values num could end up being. In this program, num can be any whole number from 1 to 100, inclusive
-  so both 1 and 100 are possible.*/
-// Math.floor(...) turns that into a whole number.
-// Finally, we add minimum so the number starts at minimum instead of 0.
+// Multiplying by 100 gives a value from 0 (inclusive) up to 100 (exclusive).
+// Math.floor(...) makes that an integer from 0 to 99.
+// Adding minimum (1) shifts the result to an integer from 1 to 100, inclusive.
