can someone let me know if this is the correct answer for this problem..
(3+8)+2=(8+3)+2 would this problem be consired Associatve?

math 
An,
Yes

math 
trina,
Thank you....

math 
An,
oh sorry... i posted twice... Your welcome... do you understand why it is associative?

math 
trina,
no ma am can you explain to me please.

math 
trina,
this is what I googles to find that answer...
*When three or more numbers are added, the sum is the same 
math 
An,
Your numbers are(3+8)+2 =(8+3)+2
(3+8)=11
11+2=13
then you have
(8+3)=11
11+2=13
In associative property you will use the same numbers to make different problems. They will always have the same answer. Does that help at all? 
math 
An,
sorrry it posted twice again...

math 
trina,
yes ma am... Thank you for breaking that down for me. So in this situation on this problem 5x26x4Look for compatible numbers to find the exact answer mentally... how would i work that out to find the answer?

math 
An,
well... do you have to show the compatible numbers?

math 
trina,
I don't know this is all it says....
*Look for compatible numbers to find the exact answer mentally for
each expression 
math 
An,
well... i don't really understand that... you could just multiply all the numbers and get the answer...

math 
trina,
ok that's what i thought about doing as well..

math 
An,
The answer is 520 by the way....

math 
An,
Any more questions?

math 
trina,
no thank you.. Thanks again...

math 
An,
No problem!

math 
Damon,
5x26x4
well I would do in my head 20*26 = 260*2 = 520
or 20*25 + 20*1 = 500+20 = 520
or 10*26*2 = 10*52 = 520
