Answer 1

No output until you declare the variables.

Answer 2

You need to define the variables and then console log the results or insert it into your html. It's really a very incomplete code

Answer 3

This is the output:

Uncaught ReferenceEror: a is not defined.
Line: 1

Hope this helps xD

Answer 4

You need to assign value and declare the variables. Otherwise, it'll show ERROR!!!
