(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?

17. 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
