I know how to add resistors in parallel and resistors in series, but i don't understand how to differentiate between resistors in the format shown:

I haven't been able to figure it out on my own and my lecturer hasn't helped either so i hope someone here is able to. Thanks.

    \$\begingroup\$ How to differentiate between resistors? That's easy - they have labels R1 through R5. \$\endgroup\$ – user253751 Apr 27 '16 at 0:05

It often helps to re-draw the circuit in a way that makes more sense to you - it may take several tries to see the "real" circuit arrangement.

When I re-draw your circuit, the first thing I do is arrange it so that electricity flows from left to right, as God intended. :)

Here we can see that R5 is simply between Vin and Ground, so has no effect on the rest of the circuit. R4 and R3 form a voltage divider, which feeds another voltage divider consisting of R2 and R1. If you had some values for the resistors and for Vin, it would be simple to calculate Vout.
