Yes, teachers are allowed to ban calculators in their classrooms if they believe it is necessary for the learning objectives of the class.

It ultimately depends on the individual's preferences and needs. If a person relies heavily on their mobile calculator for gaming strategies or calculations, then they may want to avoid game cafes that ban them.

No, a Rust ban is not necessarily an IP ban. A Rust ban can be issued to a specific player's account, preventing them from accessing the game using that account.

So while a Rust ban is not automatically an IP ban, it is possible for both types of bans to be implemented. **

A trade ban with a VAC ban or game ban means that the player is restricted from trading items in the game's marketplace.
