Since we know that law of order states that sum or product of any two specific numbers will be same irrespective to their order.
a+b=b+a and
a*b=b*a .

Law of order is only applicable for addition and multiplication. It is not applicable to subtraction and division. Let us see it by an example.


50-25\\eq25-50


25\\eq-25

Law of grouping states that it does not matter how to order a group of numbers while adding or multiplying.
a+(b+c)=(a+b)+c and
a*(b*c)=(a*b)*c.

Law of grouping is not applicable to subtraction and division. Let us see it by an example.


15-(5-3)\\eq(15-5)-3


15-(2)\\eq(10)-3


13\\eq7

Therefore, we can see that law of order and law of grouping is not applicable to subtraction.
