**trina**, Friday, January 29, 2010 at 7:53pmthis is what I googles to find that answer...

*When three or more numbers are added, the sum is the same

- math -
**An**, Friday, January 29, 2010 at 7:58pmYour 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?

**An**, Friday, January 29, 2010 at 8:08pmwell... i dont really understand that... you could just multiply all the numbers and get the answer...

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
