That means that (for certain operations), changing the order of the operands doesn't change the result. For example, for any two numbers "a" and "b", a + b = b + a (here is an example with numbers: 5 + 3 = 3 + 5). The situation is similar with the multiplication of real numbers; also with some other operators such as boolean operators (AND, OR), set operators (union, intersection), and several others.

Both are measures of central tendency. But, the mean has mathematical properties that are better understood.
In mathematics, the equality properties refer to certain rules and properties that govern the behavior of equalities. These properties include the reflexive property (a = a), the symmetric property (if a = b, then b = a), and the transitive property (if a = b and b = c, then a = c). These properties ensure that equality is a well-behaved and consistent relation.
There are different properties for each of the four basic operations. If you have to identify one, you just have to name it.
