Binary operations can have commutative and associative properties. Binary operations are essentially rules that tell you how to combine two elements to make a third (they need not all be different). Addition, subtraction, multiplication and division are the more common ones. Exponentiation, taking logarithms, etc are less well known.
Commmutativity implies that
a * b = b * a
Associativity implies that
(a * b) * c = a * (b * c) and so either can be written as a * b * c
Addition and multiplication of numbers are associative as well as commutative whereas division is neither. However, multiplication of matrices is not commutative.

What are the math properties?
They are the associative property, distributive property and the commutative property.
What is the difference between the commutative property and associative property?
In the case of addition: Commutative property: a + b = b + a Associative property: (a + b) + c = a + (b + c) Note that (1) the commutative property involves two numbers; the associative property involves three; and (2) the commutative property changes the order of the operands; the associative property doesn't. Repeatedly applying the two properties allow you to rearrange an addition that involves several numbers in any order.
What are the three names for additions properties?
associative property commutative property zero property
What are the properties of mathematical system to be a commutative group?
Closure, an identity element, inverse elements, associative property, commutative property
What are the properties of multipulcation?
They are the Associative Property of Multiplication, the Commutative Property of Multiplication, and the Zero Property of Multiplication.
