A calculator, in essence, is a tool used for computation, purely designed for that purpose.
Whether simulating spells or controlling mechanical techniques and arrays, these are just additional capabilities. These functions were later integrated by Modern Cultivators.
Throughout history, many broad tools for calculation existed in ancient Shenzhou. Early counting rods, abacus, and even the "Craftsmanship Ruler," glimpsed within the Middle Ages Mo School's mechanical techniques, belong to this category.
The so-called "Craftsmanship Ruler" is a magical tool often used in mechanical techniques. It consists of three interlocking marked strips and a sliding cursor. This fascinating ruler serves to calculate and even record the dimensions of mechanical components.
