Question

verify the addition is commutative for whole numbers

Answer 1

Let A be the number 12.
Let B be the number 18.
Both A and B are whole numbers.
Commutative property = A+B = B+A
12+18 = 30
18+12 = 30
Thus A+B =B+A

Answer 2

Answer:

Hence verified that the addition is commutative for all whole numbers or any type of numbers.

Solution:

An operator is said to be commutative if  

$A \otimes B = B \otimes A$

We have to prove commutativity of addition where operator

$\otimes = +$

That is

$A+B=B+A$

Take any value of A and B , for example A = 5 and B = 20.

We get,  

$A + B = 5 + 20 = 25$

And ,

$B + A = 20 + 5 = 25$

Thus,

$A + B = B + A$

Hence, addition is commutative for all whole numbers or any type of numbers.
