A split-complex number is an ordered pair of real numbers, written in the form = + where x and y are real numbers and the hyperbolic unit [1] j satisfies = + In the field of complex numbers the imaginary unit i satisfies =
Almost all points of the complex plane are associated with one of the deg(p) roots of a given polynomial in the following way: the point is used as starting value z 0 for Newton's iteration z n + 1 := z n − p(z n) / p'(z n) , yielding a sequence of points z 1, z 2, …, If the sequence converges to the root ζ k, then z 0 was an ...
A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i 2 = −1.
As a consequence, the only commutative division algebras are R and C. Also note that H is not a C-algebra. If it were, then the center of H has to contain C, but the center of H is R. This theorem is closely related to Hurwitz's theorem, which states that the only real normed division algebras are R, C, H, and the (non-associative) algebra O.
These are of course both associative. For a non-associative example, consider the complex numbers with multiplication defined by taking the complex conjugate of the usual multiplication: = ¯. This is a commutative, non-associative division algebra of dimension 2 over the reals, and has no unit element. There are infinitely many other non ...
For division to always yield one number rather than an integer quotient plus a remainder, the natural numbers must be extended to rational numbers or real numbers. In these enlarged number systems , division is the inverse operation to multiplication, that is a = c / b means a × b = c , as long as b is not zero.
In all semirings, including the complex numbers, the quaternions, polynomials, and matrices, multiplication distributes over addition: (+) = +, (+) = +. In all algebras over a field, including the octonions and other non-associative algebras, multiplication distributes over addition.
The greatest common divisor (GCD) of integers a and b, at least one of which is nonzero, is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer.
