I thought about why I like mathematics and computers

Equal to everyone

Regardless of the person, position, or location, it always returns the same output for the same input.

Clear rules

The rules are clearly defined, and there is no absurdity or injustice.

The answers and theories derived are forever correct

There is no worry that an answer once derived will be rewritten later.

Appropriate level of difficulty

There are always unsolved problems, and you can challenge yourself to solve them at any time.
