Yes
Thank you....
Yes
oh sorry... i posted twice... Your welcome... do you understand why it is associative?
no ma am can you explain to me please.
this is what I googles to find that answer...
*When three or more numbers are added, the sum is the same
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?

sorrry it posted twice again...
yes ma am... Thank you for breaking that down for me. So in this situation on this problem 5x26x4-Look for compatible numbers to find the exact answer mentally... how would i work that out to find the answer?
well... do you have to show the compatible numbers?
I dont know this is all it says....
*Look for compatible numbers to find the exact answer mentally for
each expression
well... i dont really understand that... you could just multiply all the numbers and get the answer...
ok thats what i thought about doing as well..
The answer is 520 by the way....
Any more questions?
no thank you.. Thanks again...
No problem!
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
