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 .
For example: "All humans are mortal, and Socrates is a human. ∴ Socrates is mortal." ∵ Abbreviation of "because" or "since". Placed between two assertions, it means that the first one is implied by the second one. For example: "11 is prime ∵ it has no positive integer factors other than itself and one." ∋ 1. Abbreviation of "such that".
The binary number system expresses any number as a sum of powers of 2, and denotes it as a sequence of 0 and 1, separated by a binary point, where 1 indicates a power of 2 that appears in the sum; the exponent is determined by the place of this 1: the nonnegative exponents are the rank of the 1 on the left of the point (starting from 0), and ...
As suggested by the previous example, the indicator function is a useful notational device in combinatorics. The notation is used in other places as well, for instance in probability theory : if X is a probability space with probability measure P {\displaystyle \operatorname {P} } and A is a measurable set , then 1 A {\displaystyle \mathbf {1 ...
In mathematics, "rational" is often used as a noun abbreviating "rational number". The adjective rational sometimes means that the coefficients are rational numbers. For example, a rational point is a point with rational coordinates (i.e., a point whose coordinates are rational numbers); a rational matrix is a matrix of rational numbers; a rational polynomial may be a polynomial with rational ...

(The Center Square) – President-elect Donald Trump, who is set to take office Monday, has made a series of promises of major executive actions on “day one” in office. One of the simplest and ...
The premises are shown above a line, called the inference line, [15] separated by a comma, which indicates combination of premises. [44] The conclusion is written below the inference line. [ 15 ] The inference line represents syntactic consequence , [ 15 ] sometimes called deductive consequence , [ 45 ] which is also symbolized with ⊢.
