Faster ways of Identifying the Network and Broadcast Address of a Subnet?

I am about to take my N10-005 and and feel fairly confident.

To identify the Network and Broadcast Address of a Subnet I have been using binary arithmetic/boolean operators. I definitely have it down, however I want to know if this is how people actually do it in the real world, or do the use their 'formulas' to obtain the answers quicker.

I was reading in another sub forum that for higher level Cisco certs you need to be able to do the math alot quicker than the min or 2 it may take me. Is the way I am doing it acceptable?

Appreciate it!
