$a+b \,=\, b+a$
The addition of two quantities is equal to their sum in reverse order. It is called the commutative property of addition.
$a$ and $b$ are two operands in algebraic form and their sum is written in mathematical form as $a+b$. Now, add them in reverse order and it is expressed as $b+a$. Mathematically, the two expressions are equal and it is called as the commutative law of addition.
$2$ and $3$ are two quantities and add them.
$\implies$ $2+3 = 5$
Now, add the same two operands in reverse order.
$\implies$ $3+2 = 5$
$\,\,\, \therefore \,\,\,\,\,\,$ $2+3$ $\,=\,$ $3+2$ $\,=\,$ $5$
Thus, the commutative rule of addition can be verified in numerical system.
