+# Greet and Arithmetic
+
+This project contains two node modules, greet and arithmetic. 
+
+The Greet module is a function which accepts a name parameter and returns "hello [name]!".
+
+The Arithmetic module is an object containing two methods, add and subtract. They both accept two parameters and return the result.
