 Declare a function named `addTwoNumbers`. This function should take two arguments and return the sum of those two arguments.

+Your function should not use hard-coded values. An example of a hard-coded function might be:
 
+```js
+function sayName(firstName, lastName) {

+This function would return `"John Doe"` regardless of the arguments passed to the parameters `firstName`, and `lastName`, so `"John Doe"` is considered a hard-coded value.
