I don't have any OP amps and I need to get a lower resistance from a resistor, if that makes sense. If I remember correctly, if you split the line, and put resistors on each side and put the two lines back together, you subtract the two resistances. But I don't think thats correct....
I`m not sure what is meant by not having an op-amp but if I understand the rest of your question correctly, yes you can reduce the resistance by putting two resistors in "parallel". There is a formula for working out the exact reduction but if, like me, you are mathematically challenged, you can go here for a handy calculator.

thanks much.

You can do that with resistors in parallel. Look at the section
