Thank you SOOOO much! I was looking to understand and you kept it very simple and did it in a way that people can relate to. Thank you again :0)

Thanks for this! I have yet to pass my math proficiency test, and need my high school diploma to do so. It's the only thing I'm missing. Anyway, this always confused me, the difference between the properties. So thanks again!

the problem I am having is that in my head I can't get past that 1+2+3 = 1+3+2
so I keep making the mistake of saying (1+2)+3 = 1+(2+3) is commutative because really you can switch any of those numbers and get the same freaking answer.

WHY even differentiate in addition when in the end it's always going to be the same?

I can understand if it's multiplication but there really is no need for this sort of thing with addition. or am I wrong?

Its so easy that its confusing lol, I don't understand why these people who make up these math terms have to make things a bit more confusing. Just say that they both switch around numbers in different ways.

so like in associative property it must includes parenthesis? if It does not includes parenthesis it will be commutative property? in other words the difference between these two are the parenthesis?

This is possibly the easiest way to provide an analogy of why these are different (yet the same). I couldn't get it through my head until you explained the Moving around vs being buddy buddy. Makes 100% more sense, even though this whole thing is kinda pointless, hahahah.
