Word of the Week: Ten

The number ten is defined as a number that is one more than nine. The word ten was first used around the 12th century and derives from the Old English tēn, which has its roots in the Sanskrit word daśa and the Latin word decem.

In Roman numerals the letter X represents the number 10. It is made up of two “V’s” (the Roman numeral for 5) one on top of each other. 

The Hindu–Arabic numeral system was invented by Indian mathematicians between the 1st and 4th century. As the system spread through Eurasia, it was adopted by Arabic mathematicians around the 9th century AD. It wasn’t until the Middle ages when the famous Italian mathematician Fibonacci popularized the Hindu-Arabic numeral system in Europe with his book Liber Abaci (Book of Calculation). In most English speaking countries the symbol 10 is made up of the Hindu-Arabic numerals 1 and 0.
