+// Math.floor is a built in function in JavaScript which basically rounds down a number to 
+// its nearest whole integer.
+
+//Math.random is also a built in function for selecting random numbers in this case
+//numbers that are between 1 and 100
+
+//Therefore num is equal to the a randomly selected number that has been
+// rounded down to its nearest whole integer times (maximum - minimum + 1) + minimum
+//the computer solves the expression in the bracket first as per mathematics order of operation
+// rules so the expression shrinks to Math.floor(math.random()*100) + 1)
+// so whatever the random value that the computer generates will be multiplied by 100 and rounded
