This may have been answered already, but I just wanted clarification because I am a bit uncertain (hehe :D). If a question gives you +/- (a number) m/s as delta V, do you use that exact number and plug it into the equation or do you multiply it by 2 to account for both the positive and negative values of the number (I don't know if that made much sense). Thank you.

Yup! The plus or minus means the value can range from (i.e. using v = 10 +-5 m, so deltaV= 10m) 5 to 15, which is a 10 m range.
