'''Zero''' (written <math>0</math>) is the [[additive identity]] of the [[real number]]s. One is the successor of zero. It is believed that [[India]]ns invented the numerical concept of zero for their trades to the west.

'''Zero''' (written <math>0</math>) is the complete absence of something.  It can also be defined as being [[infinity|infinitely]] small.

 

 

In purely mathematical terminology, zero is also the [[additive identity]] of the [[real number]]s. One is the successor of zero. It is believed that [[India]]ns invented the numerical concept of zero for their trades to the west.

'''0''' is the smallest  [[number]] in the set of non-negative [[integer]]s <math>\mathbb{N}_0 = \{0, 1, 2, 3, \ldots\}</math>.
