Roman numerals, the numeric system of ancient Rome, uses combinations of letters from the Latin alphabet to signify values. The numbers 1 to 10 can be expressed in Roman numerals as follows:
The Roman numeral system is decimal but not directly positional and does not include a zero. It is a cousin of the Etruscan numerals. Use of Roman numerals persisted after the decline of the Roman Empire. In the 14th century, Roman numerals were largely abandoned in favor of Arabic numerals; however, they are still in use to this day in minor applications such as numbered lists or outlines, clock faces, numbering of pages preceding the main body of a book, successive political leaders or people with identical names, chords in music, some Copyright dates, and the numbering of certain annual events.
Roman numerals, as used today, are based on seven symbols:
These Roman Numbers are formed by combining symbols together and adding the values. For example, MMVI is 1000 + 1000 + 5 + 1 = 2006. Generally, symbols are placed in order of value, starting with the largest values. When smaller values precede larger values, the smaller values are subtracted from the larger values, and the result is added to the total. For example MCMXLIV = 1000 + (1000 − 100) + (50 − 10) + (5 − 1) = 1944.
Kenneth Wayne "Ken" Jennings III (born May 23, 1974) is an American game show contestant and author. Jennings is noted for holding the record for the longest winning streak on the U.S. syndicated game show Jeopardy! and as being the all-time leading money winner on American game shows. In 2004, Jennings won 74 Jeopardy! games before he was defeated by challenger Nancy Zerg on his 75th appearance. His total earnings on Jeopardy! are $3,172,700, consisting of $2,520,700 over his 74 wins, a $2,000 second-place prize in his 75th appearance, a $500,000 second-place prize in the Jeopardy! Ultimate Tournament of Champions, as well as half of a $300,000 prize in the IBM Challenge.
During his first run of Jeopardy! appearances, Jennings earned the record for the highest American game show winnings. His total was surpassed by Brad Rutter, who defeated Jennings in the finals of the Jeopardy! Ultimate Tournament of Champions (first aired on May 25, 2005), adding $2,000,000 to Rutter's existing Jeopardy! winnings. Jennings regained the record after appearing on several other game shows, culminating in an appearance on Are You Smarter Than a 5th Grader? (first aired on October 10, 2008), though Rutter retains the Jeopardy! record.
