There is an on-screen calculator you can use.
As far as subnetting, you should know the basics. You may see a question asking what
192.168.10.100/24 is. The /24 would be 255.255.255.0
192.168.10.100/18. the /18 would be 255.255.192.0.
You will more likely be asked to identify a specific address, what class it is
One of the best ways is to look at the exam objectives and make sure you are solid on what they are asking.

I agree - I took the test last month and didn't get one question on actual subnetting. Honestly - I believe that the subnetting you are thinking of is outside of the scope of the Net+ exam. I used an Exam cram book, Mike Meyers video training and I leafed through some books a colleague had and none of them covered subnetting in any serious detail beyond "What is a /24 in binary and dotted decimal notation".
Honestly if you have a grasp on how to do it (which it sounds like you do), you will be fine with that part and probably have overstudied a bit.
