-// 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
+//num represents a number
+//lets start by (maximum-minimum +1) which the output is 100. 
+//math.random()*100 returns random number between 0 and 100
+//math.floor()it rounds a number to thier nearest integer,
+//at the end we add 1.

 // Try logging the value of num and running the program several times to build an idea of what the program is doing
