# Sum Of Multiples Given a number, find the sum of all the unique multiples of particular numbers up to but not including that number. If we list all the natural numbers below 20 that are multiples of 3 or 5, we get 3, 5, 6, 9, 10, 12, 15, and 18. The sum of these multiples is 78. ## Running tests In order to run the tests, issue the following command from the exercise directory: For running the tests provided, `rebar3` is used as it is the official build and dependency management tool for erlang now. Please refer to [the tracks installation instructions](http://exercism.io/languages/erlang/installation) on how to do that. In order to run the tests, you can issue the following command from the exercise directory. ```bash $ rebar3 eunit ``` ### Test versioning Each problem defines a macro `TEST_VERSION` in the test file and verifies that the solution defines and exports a function `test_version` returning that same value. To make tests pass, add the following to your solution: ```erlang -export([test_version/0]). test_version() -> 1. ``` The benefit of this is that reviewers can see against which test version an iteration was written if, for example, a previously posted solution does not solve the current problem or passes current tests. ## Questions? For detailed information about the Erlang track, please refer to the [help page](http://exercism.io/languages/erlang) on the Exercism site. This covers the basic information on setting up the development environment expected by the exercises. ## Source A variation on Problem 1 at Project Euler [http://projecteuler.net/problem=1](http://projecteuler.net/problem=1) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
