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

+// Answer: num is represents a random integer inclusive between minimum and maximum

 // 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
+// Answers: const minimum = 1 (thats's the minimum number constent variable)
+//          const maxiumum = 100 (that's the maxiumum number constant variable)
+//          Math.random: generates a random decimal number between 0 and 1
+//          (maximum - minimum + 1) Calculates the range of possible numbers (100 - 1 + 1=100)
+//          Math.random() * (maximum - minimum + 1) scales a random decimal to range a between 0 and 99.99
+//          Math.floor: Rounds the decimal down to the nearest whole interger (0 to 99)
+//          + minimum: shifts the range up by 1, resulting in the whole number from 1 to 100

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