+# Sum of the Numbers
+
+## Overview
+* The program should respond by returning the sum of numbers 1 to n. (That is, if a user inputs 2, the method should return 3. 1 + 2.)
+*Modify oneToNumber() to satisfy the given unit tests.
+* **Constraint:** No [Guassian wizardry](http://mathandmultimedia.com/2010/09/15/sum-first-n-positive-integers/) !
+
+## Unit Test
+Provided in SumOfInputTest.java
