A Timeline of Invention
Every digit you write has a story. Long before zero was a number, civilisations carved tally marks into bone and clay. Over four millennia, four great traditions converged to give us the elegant base‑10 system we use today.
Base‑10 with dedicated hieroglyphs for powers of ten: a stroke for 1, a heel bone for 10, a coil of rope for 100, and a lotus flower for 1,000. Numbers were built by repeating symbols, additive, no zero needed.
𓍯𓎉𓏿 = 342The revolutionary invention of a place‑value system with nine digits and, crucially, a symbol for zero (śūnya, “void”). This made arithmetic efficient and scalable in a way no earlier system could match.
४५६ = 456Additive and subtractive notation using letters: I, V, X, L, C, D, M. Still used for centuries in commerce and architecture. No zero, no place value, yet it dominated the Mediterranean for over a thousand years.
MCDLXXXVII = 1487Scholars in the Islamic world adopted Hindu numerals, refined the shape of digits, and spread them across trade routes. By the 13th century, Fibonacci popularised “al‑Khwarizmi’s” method in Europe. The rest is mathematics.
