1.AdjectiveSuch that the order in which the operands are taken does not affect their image under the operation.
"Addition on the real numbers is commutative because for any real numbers
s
,
t
{\displaystyle s,t}
, it is true that
s
+
t
=
t
+
s
{\displaystyle s+t=t+s}
.; Addition and multiplication are commutative operations but subtraction and division are not."
2.AdjectiveHaving a commutative operation.
3.AdjectiveSuch that any two sequences of morphisms with the same initial and final positions compose to the same morphism.
