Kirchoffs Voltage Law and Current Law - is there easier math for this?

I think I understand the simple examples for this law, thought the math (algebra) is a bit daunting as its been many many years since high school, and I wasn't very good at it then. The more complex examples make me dizzy.  I have to believe there is an easier way to understand and use this law in my robots circuits. Or is this something that I will rarely use? Is there an easy "rule of thumb"?

Here is an example from the class, not even terribly complex, but seems that way for me.
