Westerners all know that the Romans used different numbers from the ones
we use now. For example, V was 5, X was 10 and L was 50. But what few
people know is where the numbers we use now (0, 1, 2, 3...) come from.
Most people believe that these numbers were invented by the Arabs, hence the common misnomer "Arabic numerals". However, they were not invented by the Arabs, but but the Indians, 1100 years before the rise of Islam and 400 years before the Roman Empire, around 400 BC.
What made them revolutionary was the discovery of the number "0". This shorten complex numbers (e.g. 78 in Roman numerals is LXXVIII) and accelerated calculation. Ultimately, it made possible invention of the computer.
