+// const minimum = 1 sets the minimum value to 1
+// const maximum = 100 sets the maximum value to 100
+//Math.random() generates a random decimal number, zero inclusive but not 1.
+// (maximum - minimum + 1) calculates how many whole numbers maximum  and minimum
+// Math.random() * (maximum - minimum + 1) ensures that the random decimal is within  the desired range.
+// Math.floor(...) rounds the number down to the nearest whole integer
+// + minimum shifts the range upward so it starts at minimum instead of 0
+// The program generated random numbers from 0 to 100 as whole integers.
