We use the associative property of multiplication, which is: x*(y*z)=(x*z)*y.

So, here we have: (pq)r and (qr)p.

 

It doesn't matter where the brackets are around the numbers, it is still going to yield the same value.

 

Here's an example: 2,3,4

 

We have (2*3)*4=(3*4)*2=6*4=12*2

 

24=24, yay!
