Can subtraction be commutative - Mathematics Stack Exchange
2019年2月12日 · In primary and secondary school we all learnt that subtraction is not commutative, as only addition and multiplication is. However, could subtraction be commutative for all real numbers that are subtracted from itself. E.g 5-5=0 And 5-5=0. There are an infinite number of these pairs, so could subtraction be commutative when: x=y As in x-y?
On The "Commutative" Properties Of Subtraction And Division
2018年6月22日 · Can someone explain to me why subtraction and division is both commutative? The reason I believe that they are commutative are as follows: $$ 3-2 = 3+(-2) $$ $$ 3+(-2) = (-2)+(3) $$ I've read a website that says this doesn't prove the above because I'm still "commutating the addition".
Commutative property of subtraction and addition of negatives
2020年10月14日 · However, when you view it in this way the noncommutative property of subtraction is broken. Therefore can they not be considered equivalent? An example: Subtracting two numbers $$ 2-3= -1 $$ $$ 3-2 =1 $$ Viewing it as adding a negative $$ 2+(-3)=-1 $$ $$ (-3)+2=-1 $$ Therefore upon viewing it as adding a negative one of the principal parts of ...
How does commutative property not hold for subtraction?
2024年2月21日 · I don't get why commutative property is not valid under subtraction, because I find that it is for example: $5 - 3 = 2 = -3 + 5$ or rather $5 + (-3) = 2 = -3 + 5$ So how does it not hold true for
How to explain to kid why subtraction is not commutative
2018年4月27日 · It is easy to explain why addition is commutative. It is also easy to give real world examples of non-commutative operations (putting on underwear and trousers, etc). But I cannot figure out example with subtraction.

Commutative Property of Natural Number Multiplication
Can the commutative property be proven only by the things I showed above? I think it should be possible because natural number multiplication has this property. On the other hand, I know subtraction can be defined without defining full integers. Still, I am looking for a proof that uses only above properties.
Does the associative property work with subtraction? - Answers
The associative property requires that the order of operation can be changed without affecting the final result. This is clearly not the case with subtraction since: (5 - 3) - 2 = 2 - 2 = 0 while ...
