What i know is that potential stays the same across parallel sections and is summed up in series. How does that help me if i can't distinguish which one is in parallel or in series? Would you mind to explain a little further please, I'm kind of new to this.

Updated the image with the resistors numerated in red. Do you have to consider potential?

Ah! That makes sense! Thank you very much!
