👉 Celtic mathematics, rooted in ancient Celtic cultures, is a unique system of numeracy and geometry that predates modern arithmetic. It primarily uses a base-20 (vigesimal) system, influenced by the number of fingers on hands and toes, and incorporates a rich symbolic language for representing numbers. Unlike the decimal system, Celtic numerals often use combinations of dots (0-9) and crosses (representing 10), with symbols like the spiral for 11 and the double cross for 20. This system is deeply intertwined with Celtic art and symbolism, reflecting a holistic approach to mathematics that emphasizes patterns and relationships. Celtic geometry also features intricate designs like the Triskele, which symbolizes cycles and the interconnectedness of life, illustrating a profound understanding of mathematical principles beyond mere calculation.
