What is the use ORDER in business rule?

[DINESH CHINNAD1]

I know BR will work low order to high order.

Example 10,11,12 and so on.
I understand something about the use ORDER in BR. But not fully.

My question is

I have 100 BR in order of 100 and I have 10 BR in order of 1000. What BR will execute first?

I know the BR with order 100 will start first. But when the order 1000 will start?

All the 100 BR with order 100 finished first and then only 10 BR with order 1000 will execute?

Thanks in Advance
