com·mu·ta·tive property

(kə-myo͞o′tə-tĭv, kŏm′yə-tā′tĭv)
The property of addition and multiplication which states that a difference in the order in which numbers are added or multiplied will not change the result of the operation. For example, 2 + 3 gives the same sum as 3 + 2, and 2 × 3 gives the same product as 3 × 2. See also associative property, distributive property.

{Actually, both proofs could also result straightforwardly from the commutative property of the neutrosophic triplet group.}
The question should be, "How are they to be taught and learned?" There are far more conceptual ways of developing multiplication facts than purely the "drill and kill" approach and a thorough undertanding of the commutative property is one way we can help children learn these facts.
4 + 6 = -- + 6 4 + 7 = -- + 8 28 + 3 = -- + 2 28 + 15 = -- + 14 9 + -- = 8 + 4 8 = -- In this activity, students explore the Commutative Property by examining true/false equations.
The first two problems sought to establish how multiplication without zero was solved and explained and if the subject used the commutative property of multiplication as an explanation.

The commutative property, counting on, doubles, and making a ten are among the strategies included in the Addition book.
For the last two examples, Thomas did not employ his knowledge of the product of 23 and four and the commutative property to derive the product of four and 23.
Some students explored the commutative property, a x b = b x a, and still others found the products of single-digit numbers and multiples of 10 and 100:
For example, students might learn about the commutative property for multiplication (3x4 = 4x3) by counting objects in equal groups and observing that four groups of three is the same as three groups of four.
