Zero to Three also publishes a variety of resources for parents, [1] professionals and policy makers, most notably the DC:0–5™ Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood. The organization's research is widely cited in the field of early childhood development and infant health.
Wikipedia Zero was a project by the Wikimedia Foundation to provide access to Wikipedia free of charge on mobile phones via zero-rating, particularly in developing markets. [ 1 ] [ 2 ] The objective of the program was to facilitate access to free knowledge for low-income pupils and students, by means of waiving the network traffic cost.
0 (zero) is a number representing an empty quantity.Adding (or subtracting) 0 to any number leaves that number unchanged; in mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures.

From Zero to Infinity: What Makes Numbers Interesting is a book in popular mathematics and number theory by Constance Reid. It was originally published in 1955 by the Thomas Y. Crowell Company. [ 1 ] The fourth edition was published in 1992 by the Mathematical Association of America in their MAA Spectrum series.
Physical location of Zero Kilometre Stone in Hungary, at the entrance of the tunnel near Lánchíd, Budapest. The Zero Kilometre Stone is a 3 m high limestone sculpture in Budapest that represents Kilometre Zero in Hungary. It consists of a zero sign, with an inscription on its pedestal reading "KM" for kilometres.
Zero also fits into the patterns formed by other even numbers. The parity rules of arithmetic, such as even − even = even, require 0 to be even. Zero is the additive identity element of the group of even integers, and it is the starting case from which other even natural numbers are recursively defined.
Zero to the power of zero, denoted as 0 0, is a mathematical expression that can take different values depending on the context. In certain areas of mathematics, such as combinatorics and algebra , 0 0 is conventionally defined as 1 because this assignment simplifies many formulas and ensures consistency in operations involving exponents .
