KnowraComplex numberLinked fromLinked fromThe 85 pages that link to Complex number, each with the reason it gives.All 85Broader topic 5Related 26Narrower topic 45Compared with 9Real numberCompared with: Complex numbers extend the reals with values that do not lie on the real line.IntegerCompared with: Complex numbers extend beyond the real line that contains the integers.Finite fieldCompared with: The complex numbers are algebraically closed and infinite, unlike finite fields.Cross productCompared with: In two dimensions, complex multiplication can encode rotation and scaling without a vector cross product.VectorCompared with: Complex numbers can be drawn as plane arrows, but their algebraic role differs from general vectors.p-adic numberCompared with: The complex field extends the real completion, while p-adic fields arise from prime-based absolute values.Algebraic closureCompared with: The complex field is algebraically closed, making it a familiar example of an algebraic closure of the reals.Negative numberCompared with: Negative real values lie on the real axis, unlike non-real complex values.Sign (mathematics)Compared with: Complex numbers do not have the ordinary positive-or-negative ordering of real numbers.
