In general AB =/= BA, for example,
orbital angular momentum operators, L_x, L_y.
but is A + B = B + A always true?

Commutativity is a mathematical property that states that the order in which two operands are used in an operation does not affect the result.
No, not all operators are commutative. Some examples of non-commutative operators include multiplication, division, and subtraction.
Yes, the addition operator is always commutative. This means that when adding two numbers, the order in which they are added does not change the result.
You can determine if an operator is commutative by looking at its properties. If the order of operands does not affect the result, then the operator is commutative.
Commutativity is important in mathematics because it allows us to simplify and manipulate equations more easily. It also allows us to generalize rules and properties to a wider range of cases.
