The commutative property works for adding and multiplying e.g. 2+4=4+2 and 3x4=4x3.
But it doesn't work for subtraction and division so 5-3≠3-5 and 6÷2≠2÷6 so subtraction and division could be considered as exceptions.

Depending what exactly you mean...* The commutative property for addition (or for multiplication) with real numbers always applies - NO EXCEPTIONS.
* In math, there are operations known as "multiplication" which share some characteristics with the common multiplication, but for which the commutative property usually does NOT apply. For example, cross-multiplication of vectors, or multiplication of matrices. In the case of matrices, it's even possible that A x B is defined, whereas B x A is not defined (because the matrices are of incompatible sizes). For two square matrices, both A x B and B x A are defined, but the results may be quite different.
The commutative property of addition and the commutative property of multiplication.
The commutative property of multiplication says that the numbers in a problem can change, but the answer will stay the same.
The commutative property states that ab = ba.
Commutative property is taking a question and flipping its factors and getting the same answer. Example: 7+(5+9)=21=(5+7)+9=21 Commutative Property of Addition
is the following commutative property 6+(-13)=-13+6
