 ## Hints
 
 Think about how you would do this on pen and paper and then how you might translate that process into code:
+- make sure you pay attention to the function parameters
 - create a variable to hold the final sum
 - loop through the given numbers ([link](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Loops_and_iteration))
 - on each iteration add the number to the sum
