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. [2]
A number line from −3 to 3, with 0 in the middle. The number 0 is the smallest nonnegative integer, and the largest nonpositive integer. The natural number following 0 is 1 and no natural number precedes 0. The number 0 may or may not be considered a natural number, [70] [71] but it is an integer, and hence a rational number and a real number ...
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 .
Many sports that originated in the UK use the word "nil" for 0. Thus, a 3-0 score in a football match would be read as "three-nil". Nil is derived from the Latin word "nihil", meaning "nothing", and often occurs in formal contexts outside of sport, including technical jargon (e.g. "nil by mouth") and voting results.

Negative numbers: Real numbers that are less than zero. Because zero itself has no sign, neither the positive numbers nor the negative numbers include zero. When zero is a possibility, the following terms are often used: Non-negative numbers: Real numbers that are greater than or equal to zero. Thus a non-negative number is either zero or positive.
Zero-based numbering is a way of numbering in which the initial element of a sequence is assigned the index 0, rather than the index 1 as is typical in everyday non-mathematical or non-programming circumstances.
A list of articles about numbers (not about numerals). Topics include powers of ten, notable integers, prime and cardinal numbers, and the myriad system.
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.
