 // Try breaking down the expression and using documentation to explain what it means
+/*Answer:
+It uses 2 methods to achieve this
+Math.random generate a random number between 0 and 1 eg. 0.343, 0.5. 0.67
+Math.floor rounds the number to a whole number.
+In this declaration:
+Math.random will return a random decimal number and multiplies it by the sum of 
+((maximum-minimum)+1). eg 0.343_*((100-1)+1) = 34.3.
+Math.floor will take the total 34.3 and round it to a whole number 34*/
