When installing a battery positive or negative first?

How do you get a battery out of a battery compartment?
Remove any screws holding the compartment shut. Usually, the screws in a battery compartment are Phillips screws, meaning they have a cross-shaped dip in the head.

Why do batteries always go in alternating directions?
Almost all the time, each row of batteries (or each battery) goes in in alternating directions. That makes sense, if you look at how they’re wired there’s usually just a piece of metal connecting one row to the next so you basically have one big long battery with a negative at one end and the positive at the other end.
