What are random objects?

What is an abacus? I saw that word in a zepla video I don’t understand anything or how to do anything and I’m a whiny baby that insists reddit do everything for me. While I’m at it, what is a Rubik’s cube, a baseball, how do you use the “f” key, what is a calculator, why do I only have a beard on my neck, is ffxiv a video game, should I leave my parents basement, why is everything that goes wrong not my fault, who is yoshi p, how do I “eat”, what is a computer, does black mage have non ice spells, which way is up?????
