The reason antimatter is "anti" is that an antiparticle has the oppose 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?
Annihilation means exactly that - both particles destroy each other on contact, releasing the energy that composed them.
