2. Multiplicative inverse - Wikipedia

   en.wikipedia.org/wiki/Multiplicative_inverse

   For every x except 0, y represents its multiplicative inverse. The graph forms a rectangular hyperbola. In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the ...

3. Modular exponentiation - Wikipedia

   en.wikipedia.org/wiki/Modular_exponentiation

   For example, given b = 5, e = 3 and m = 13, dividing 5 3 = 125 by 13 leaves a remainder of c = 8. Modular exponentiation can be performed with a negative exponent e by finding the modular multiplicative inverse d of b modulo m using the extended Euclidean algorithm. That is: c = b e mod m = d −e mod m, where e < 0 and b ⋅ d ≡ 1 (mod m).

   The season premiered with a movie special on April 19, 2019, with the remaining episodes set to begin airing in the fall; [6] However, all but two of the episodes premiered in 2020. [7] A thirteenth season was confirmed by Robert Tinkler, the voice actor of Delete, on X, which premiered on February 25, 2022. [8]

5. Modular multiplicative inverse - Wikipedia

   en.wikipedia.org/wiki/Modular_multiplicative_inverse

   A modular multiplicative inverse of a modulo m can be found by using the extended Euclidean algorithm. The Euclidean algorithm determines the greatest common divisor (gcd) of two integers, say a and m. If a has a multiplicative inverse modulo m, this gcd must be 1. The last of several equations produced by the algorithm may be solved for this gcd.

6. Multiplicative group of integers modulo n - Wikipedia

   en.wikipedia.org/wiki/Multiplicative_group_of...

   Integer multiplication respects the congruence classes, that is, a ≡ a' and b ≡ b' (mod n) implies ab ≡ a'b' (mod n). This implies that the multiplication is associative, commutative, and that the class of 1 is the unique multiplicative identity. Finally, given a, the multiplicative inverse of a modulo n is an integer x satisfying ax ≡ ...

7. Unit (ring theory) - Wikipedia

   en.wikipedia.org/wiki/Unit_(ring_theory)

   The multiplicative identity 1 and its additive inverse −1 are always units. More generally, any root of unity in a ring R is a unit: if r n = 1, then r n−1 is a multiplicative inverse of r. In a nonzero ring, the element 0 is not a unit, so R × is not closed under addition.

8. Fast inverse square root - Wikipedia

   en.wikipedia.org/wiki/Fast_inverse_square_root

   Lighting and reflection calculations, as in the video game OpenArena, use the fast inverse square root code to compute angles of incidence and reflection.. Fast inverse square root, sometimes referred to as Fast InvSqrt() or by the hexadecimal constant 0x5F3759DF, is an algorithm that estimates , the reciprocal (or multiplicative inverse) of the square root of a 32-bit floating-point number in ...

9. Dirichlet character - Wikipedia

   en.wikipedia.org/wiki/Dirichlet_character

   A Dirichlet character is a completely multiplicative function : satisfying the following three properties: a) takes only finitely many values; b) vanishes at only finitely many primes; c) there is an for which the remainder
