Epigraphy educational math toys

Abstract

Multifunctional interactive educational devices that support and enhance the teaching of arithmetic operations—addition, subtraction, multiplication, and division. These include a manipulable board for visualizing inverse relationships, a structured calculator board for regrouping, a slide-based addition mechanism, and a symbolic comparator tool. These tools help overcome common learning difficulties through intuitive mechanical and visual interfaces. Designed for educational use, these inventions aim to improve numeracy skills among early learners.
