The reason antimatter is “anti” is that an antiparticle has the opposite charge of its non-anti counterpart. Electrons have a negative charge, while their antiparticles, positrons have a positive charge. And since opposite charges attract, well, I think you can figure it out from there.
And yes, matter/antimatter interactions result in annihilation.
What exactly does “annihilation” mean in this context. Do both “atoms” give off energy and convert to sub atomic particles? Does one atom kind of “win” over the other and undergo fission instead of complete annihilation?
Hmm interesting. I wondered if it would be attracted or repelled by matter. It does annihilate when it comes in contact with mater, right?

Annihilation means exactly that - both particles destroy each other on contact, releasing the energy that composed them.
Isn’t “falling up” just another way of saying that it’s repelled by matter?
Yes
