Question

Do the law of order and the law of grouping apply to subtraction?

Answer 1

Answer:

Because is easy to solve the problems when you break them with parantheses.

Step-by-step explanation:

Answer 2

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.

$50-25\neq25-50$

$25\neq-25$

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.

$15-(5-3)\neq(15-5)-3$

$15-(2)\neq(10)-3$

$13\neq7$

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