Hi, this example might help...
Series Opposing
-voltage sources will subtract
(higher voltage minus lower voltage)
-same polarity connection

ex. draw a series circuit ---------->
(source1) V1=10v (-)(upper)(+)(lower), R1= 100, R2 = 75,
(source2) V2=35v (-)(upper)(+)(lower)
------R1-----------R2---------
| |
| |
V1 V2
| |
| |
------------------------------
VT (Voltage Total) = (V2)35v - (V1)10v
= 25v
VR1 = R1/RTxVT = 100/175x25 = 14.285v
VR2 = R2/RTxVT = 75/175x25 = 10.7142v
check = VR1+VR2 = 24.9992v or 25v (VT)

sorry for the drawing :). dunno yet how to solve parallel
or series parallel, if there is.. (0,,0).
