In abstract algebra, a Jordan algebra is a nonassociative algebra over a field whose multiplication satisfies the following axioms: x y = y x {\displaystyle

every nonzero element). Nonassociative rings: These are like rings, but the multiplication operation need not be associative. Lie ring: a ringoid whose additive

product is an example of a nonassociative algebra over the field of real numbers since the vector cross product is nonassociative, satisfying the Jacobi identity

All division rings are simple. That is, they have no two-sided ideal besides the zero ideal and itself. All fields are division rings, and every non-field

octonions in this manner the E8 lattice takes on the structure of a nonassociative ring. Fixing a basis (1, i, j, k, ℓ, ℓi, ℓj, ℓk) of unit octonions, one

In abstract algebra, the algebra of hyperbolic quaternions is a nonassociative algebra over the real numbers with elements of the form q = a + b i + c
