+In the arithmetic.js file the exported values will be numbers that is will have a sum. It will also have two numbers that will have the difference. If the data-type is not a integer the function will not work.
+
+In the greet.js it takes in one argument that will be a string and concatenate it with the string hello. If the argument is not a string then the function will not work and return an error.
