The Karelbug calculation board consists of an ordered structure of registers and configured similarly to the pre-Hispanic computer called Nepohualtzintzin. Only with some changes that allow greater flexibility and adaptation to the systems we are used to. Making it more practical by presenting it as a digital table for manual use.

Using this board in the correct way is fun and represents a challenge to thinking in addition to allowing us to perform fundamental mathematical operations with the facilities and advantages of working in
multi-state mode. When used in a basic way, the algorithms are applied in a similar way to how they are used in today's computers.
