Answer:
3 x 4 is the same as the 4 x 3 and 3 + 4 is the same as 4
+ 3. But 3 ÷ 4 is not the same as 4 ÷ 3 and
3  4 is not the same as 4  3. Multiplication and addition
of numbers are said to be commutative. Division and subtraction
of numbers are not commutative (noncommutative).
In mathematics, commutativity is the ability to change the
order of something without changing the end result. It is
a fundamental property in most branches of mathematics and
many proofs depend on it. The commutativity of simple operations
was for many years implicitly assumed and the property was
not given a name or attributed until the 19th century when
mathematicians began to formalize the theory of mathematics.
An operation x on a set is commutative when it does not matter
which way round two elements in the set are combined, i.e.,
when a x b = b x a for all elements a and b in the set.
