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.
The word zero came into the English language via French zéro from the Italian zero, a contraction of the Venetian zevero form of Italian zefiro via ṣafira or ṣifr. [1] In pre-Islamic time the word ṣifr (Arabic صفر) had the meaning "empty". [2] Sifr evolved to mean zero when it was used to translate śūnya (Sanskrit: शून्य ...
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.
Minute is a unit of time defined as equal to 60 seconds. [1] One hour contains 60 minutes. [2] Although not a unit in the International System of Units (SI), the minute is accepted for use in the SI. [1] The SI symbol for minutes is min (without a dot). The prime symbol ′ is also sometimes used informally to denote minutes. [3]
2. Denotes the range of values that a measured quantity may have; for example, 10 ± 2 denotes an unknown value that lies between 8 and 12. ∓ (minus-plus sign) Used paired with ±, denotes the opposite sign; that is, + if ± is –, and – if ± is +. ÷ (division sign)
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.

A number is non-negative if it is greater than or equal to zero. A number is non-positive if it is less than or equal to zero. When 0 is said to be both positive and negative, [citation needed] modified phrases are used to refer to the sign of a number: A number is strictly positive if it is greater than zero.
In the same way, zero is an integer multiple of 2, namely 0 × 2, so zero is even. [2] It is also possible to explain why zero is even without referring to formal definitions. [3] The following explanations make sense of the idea that zero is even in terms of fundamental number concepts.
