Math
Ten is the basis of the decimal system , which goes back to the number of ten human fingers . The Indo-European meaning ( ahd. Zehan ) should be interpreted with "two hands" , similar to the Latin decem . Ten is also a triangular number and a tetrahedral number as well as the sum of the first three prime numbers. The Roman numeral for ten is X (two V s, one on top of the other, each with the number five).
Ten is a Størmer number .

It is the sum of the first four numbers (1 + 2 + 3 + 4) and early on became a sign of perfection and consummation. The Ten Commandments play an important role in Judaism and Christianity , and there is also talk of ten biblical plagues .

Furthermore, the time between the Jewish New Year festival Rosh Hashanah and the day of Atonement ( Yom Kippur ) is called the ten reverential days . The ten thus has the meaning of order, absoluteness and totality. The Greek letter χ - cf. the Roman numerical value ten - stands as the central letter of the Christ monogram for Christ himself.
