- Every Boolean ring is commutative12. In other words, if R is a Boolean ring, then for any elements x and y in R, xy = yx.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.Boolean rings are necessarily commutative (http://planetmath.org/CommutativeRing). Also, if R R is a Boolean ring, then x =−x x = - x for each x ∈R x ∈ R.planetmath.org/booleanringA similar proof shows that every Boolean ring is commutative : x ⊕ y = (x ⊕ y)2 = x2 ⊕ xy ⊕ yx ⊕ y2 = x ⊕ xy ⊕ yx ⊕ y and this yields xy ⊕ yx = 0, which means xy = yx (using the first property above).en.wikipedia.org/wiki/Boolean_ring
