Diyakini bahwa angka Romawi berasal dari isyarat tangan dan tanda penghitungan. Goresan I melambangkan satu jari, V melambangkan celah antara ibu jari dan jari-jari untuk lima, dan X melambangkan tangan yang disilangkan untuk sepuluh. Huruf L, C, D, dan M berasal dari modifikasi huruf Yunani seperti chi, theta, dan phi untuk melambangkan 50, 100, 500, dan 1.000. Seiring waktu, tanda-tanda ini berubah menjadi huruf Latin yang dikenal orang saat ini. Tidak ada angka 0 dalam alfabet Romawi, karena konsep angka 0 baru berkembang sepenuhnya setelah India menemukannya sekitar 600 M / 10600 HE.
