 // In this exercise, you will need to work out what num represents?
 // Try breaking down the expression and using documentation to explain what it means
 // 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
+// 
+//`num` represents a random integer between 1 and 100 (inclusive).
+//
+// Breakdown of the expression (from inside out):
+// 1. Math.random() returns a decimal between 0 (inclusive) and 1 (exclusive).
+// 2. (maximum - minimum + 1) = (100 - 1 + 1) = 100, the size of the range.
+// 3. Multiplying them gives a decimal between 0 and 100 (not including 100).
+// 4. Math.floor() rounds it down to a whole number between 0 and 99.
+// 5. Adding `minimum` (1) shifts the range so the result is between 1 and 100.
