+# Sum Of Multiples
+
+Write a program that, given a number, can find the sum of all the multiples of particular numbers up to but not including that number.
+
+If we list all the natural numbers up to but not including 15 that are
+multiples of either 3 or 5, we get 3, 5, 6 and 9, 10, and 12.
+
+The sum of these multiples is 45.
+
+Write a program that can find the sum of the multiples of a given set of
+numbers.
