Answer 1

Something to keep in mind.
When you use getElementsByClassName you are asking a collection of elements, so when you try to get an individual elements value you need to state which element you are referring to, in most case it is the first element at the 0 index.

So...
document.getElementsByClassName('btn-one').value; <-- don't do this.
document.getElementsByClassName('btn-one')[0].value;<-- do this.

Answer 4

Javascript can be confusing. What exactly is confusing you at this moment?

Answer 5

Now I must admit I am somewhat confused.
What you are trying to do with the calculator is no different than what you have done with your card project (getPrice() function). You should follow that same concept.
