How Do You Calculate with Uncertainties in Lab Work?

[omarsalem91]

Homework Statement

Basically I'm doing a lab and it states that I am not to omit uncertainties from my calculations. It has been ages since I've calculated with uncertainties so when I went back to my notes, they weren't there! Now I am completely lost and clueless. I know there are such things as percent and integer based uncertainties but other than that I don't have any equations or examples to make myself clearer. I really hope that you guys can be of help to me.
Thanks
