+There are two modules you can use:
+
+Greet Module:
+  - *.greet('string') you can add any string as an argument(airty of one) into this method to have it say hello + 'string'.  if you do not pass an argument it will throw a null error.
+
+Arithmatic Module:
+  - *.add(x,y) you can pass in 2 number arguments(airty of two) and it will add the numbers.  if you do not pass in arguments it will throw a null error.
+
+  - *.sub(x,y) you can pass in 2 number arguments(airty of two) and it will subtract y from x.  if you do not pass in arguments it will throw a null error.
