+Num represents a random whole number between the value of 'minimum' (1) and 'maximum' (100)
+By creating a constant variable called 'num' and assigning it the value of the expression, we can generate a random number within the mentioned range. 
+
+When running the program we have to understand how the expression works:
+
+we have to work out the parentheses first, maximum - minimum + 1, which is equal to 100 - 1 + 1 = 100.
+so: Math.floor(Math.random() *100) + 1
+ Math.random() produces a pseudo-random decimal number that is greater than or equal to 0 but less than 1.
+
+ Next, we need to multiply the result from Math.random() by 100. This may give us the result of a decimal between 0 and 100.
+ Next step is to use Math.floor() wich then rounds down the decimal number to the nearest whole integer. This then means that the result will be a whole number between 0 and 99.
+But we want 1-100, so we add 1 to the result of Math.floor() this then changes the range to be inclusive of 1 and 100.
+After adding 1, we need to round down the number to the nearest interger, this is done by using Math.floor(). After this we will have a whole number between maximum and minimum.
+Therefore, the final result of num will be a random whole number between 1 and 100, inclusive.
