At present the Hindu-Arabic numerals hold nearly unlimited sway in the realm of number. In China, in Japan, in southeast Asia, and in parts of India, it is true, they are employed only by the upper classes and by foreign traders; but all over Europe, in Australia, and in North America, they are supreme; while in South America and in Africa they are used wherever civilized men make arithmetical computation.

Our numerals as we now use them are commonly known as Hindu-Arabic numerals. Most historical evidence points to India as the country of their origin. To the Arabs who were instrumental in their transmission to Europe, they were known as the "Hindu numbers."

For incising on wood or stone or metal the Roman numerals are more convenient than the Hindu-Arabic numerals.

Hindu-Arabic numerals made the printing process faster because the numbers usually required fewer digits than numbers written with Roman numerals. For example, it takes 2 digits to write the number of this page using Hindu-Arabic numerals: 22. Using Roman numerals, it would take 4 digits: XXII. By using fewer blocks of metal type, printers saved a little time on each page and a lot of time on a whole book. By around 1550 A.D., Hindu-Arabic numerals had taken the place of Roman numerals throughtout Europe.

What we today call Hindu-Arabic numerals are not only a superior calculation tool but space-efficient. If three centuries from now our descendants are still pummeling each other up and down football fields, have no doubt that television producers will by then have tired of squeezing ungainly legends like "Super Bowl CCCXXXIV" onto TV screens. "Super Bowl 334" is vastly more economical, even if it suggests more pedestrian athletic combat than the epic struggle conveyed by Roman numbers.

Unlike Roman numerals, Hindu-Arabic numerals change their meaning. The '2' in 1234 means 'two hundred', while the '2' in 4321 means 'twenty'.
