Average atomic mass formula?

I forgot it and didn't write it down in 10th grade chem today. I remember it had something like isotope a+(idkwatgoeshere)Isotopeb---and so on to 3 isotopes.

    It's just a weighted average. Multiply each isotope's weight by its percent abundance. Usually, one is much more prevalent than the rest, but not always. The sum of these numbers is the average molecular weight.
