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.

Building strapping

Im not sure what it's called, CTC can you enlighten me? But it's cheap and easy to work with. I've used it on Retro bot for the extra battery holder http://letsmakerobots.com/node/8004 You should be able to get it from you local building supplies store. Easy to bend, and cut it with tin snips.
