Answer 1

The function name is:
getElementsByClassName
And this is how you call it:
btn = document.getElementsByClassName('btn')

btn now holds a NodeList(array-like object containing all elements of class "btn") and you need to use [ ] notation to access individual elements.

Your logic is wrong.
In onclick attribute pass a value (maybe a number) to know wich button was clicked.
Use a named parameter in your function declaration to gather the result and do the logic.

Remember: btn[0] is your first button.
btn[1] is your second one, etc.
