 // 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

+// Math.random() generates a random decimal number from 0 to less than 1
+// Math.floor() rounds down to the nearest whole number
+// maximum-minimum+1 gives 100
+// Math.random() * (maximum - minimum + 1) gives a random decimal number between 0 and less than 100, and Math.floor() rounds it down to the nearest integer to give a range of 0 to 99, and by adding minimum 1 to it, num is a random integer between 1 and 100 inclusive
