LOL!!
If math is not your strong point, you can use a reactance chart like this one to approximate the impedance.

The inductance is the lines slanted one way, the capacitance is the lines slanted the other, and the frequency is on the bottom (vertical lines). Where they all meet is the impedance in ohms along the left side (horizontal lines).
Does that relieve that headache a bit?
edit: My bad. I was so busy laughing, I gave you incorrect info. The impedance is where the capacitance and inductance lines cross. Where the frequency line crosses is the resonant frequency. At least that is what I remember.
