Ive read and heard different opinions on this one... and according to most... it states that they are not allowed to bring a calculator to take the test with. It is usually understandable since most calculators are advanced enough to hold notes and such. For example, my calculator is an HP iPaq that I use for my own personal notes and I even have a .pdf version of Sybex on there.

Bottom line, I wouldnt count on it to bring a calculator. I would however, learn how to set up the table and just write it on a piece of paper once I sit down in front of the PC. Just remember not to start the test and then write it down.... you should write down everything you want and put it on a piece of paper before you start the test.

The table I use goes something like this: (aesthetically it might not look nice in this format)

Note: (n-2) being that you must subtact 2 from the count to get the appropriate amount of hosts and/ or subnets. Of course for a non subnet zero examples.
