How do I calculate these Uncertainties?
Okay, so I have this equation:
F = F1 + F2 - dF1F2
Anyways, I have the uncertainties for F1 and F2, how would I go about getting the uncertainty for F?
Do I just simply add the uncertainties or do I use the formula deltaF1/F1 +deltaF2/F2 = deltaF/F?
Thanks for your help.

First find the uncertainty in the product term using the appropriate rule for multiplication then treat that partial result as a new value with its own uncertainty. Use the rule for addition/subtraction when you sum the remaining values.
