Fixes 65851414_about_methods_master

* I learned that method arguments can be called without parenthesis, BUT you should use parenthesis when
  leaving them off would be ambiguous
* I learned that calling global methods with the wrong number of arguments is not a syntax error, but a runtime
  error
* Methods with default values as arguments will always use the default value unless overwritten by explicitly
  using another value for that default value
* Methods with variable arguments are Arrays
* Methods with explicit returns will return the value of what is returned, even if there's another value after it
* Methods without an explicit return will return the last value
* Private methods are inaccessible from other objects
