# Zero

**Zero** (written ) is the complete absence of something. It can also be defined as being infinitely small. It can also represent humility, and self-denial. It can be an effective concept against greed and addiction.

Zero was introduced conceptually by Jesus before mathematicians recognized it. His parable of about the repeated yield of zero in connection with the sower of the seed is an explanation of logic in how everything times zero is still zero. In contrast, infinity is still infinity no matter what is subtracted or divided from it. This same parable is retold in all three synoptic Gospels, at Matthew 13:1-23, Mark 4:1-20, and Luke 8:1-15.

Zero is a powerfully beneficial concept in many contexts. Freedom is zero confinement. As another example, zero worries is a goal to strive for. Successful abstinence is zero. A clear mind consists of zero anxiety. An optimal decision-maker is one having zero biases. The expression "peace be with you" can be understood as a state of zero internal turmoil.

In purely mathematical terminology, zero is also the additive identity of the real numbers. One is the successor of zero. It is believed that Indians invented the numerical concept of zero for their trades to the west.

**0** is the smallest number in the set of non-negative integers .

Developed by Arab mathematicians, the concept of zero was an important development in mathematics as it provided an easy method to increase magnitude in a simple and consistent manner, a significant advance in the practice of arithmetic and a step towards more sophisticated mathematics.

In the BC/AD timeline of the Gregorian calendar, the year zero is omitted. History proceeds from December 31, 1 BC to January 1, AD 1. This can lead to counting errors when summing up spans of time that cross the transition point, because people often assume the timeline is constructed like the set of integers.
