What is the rule for combining resistors in series and parallel circuits( combination circuits)?

In series, you add the values of the individual resistors. In a parallel circuit of R1, R2, R3..., the equivalent resistance R is given by
1/R = 1/R1 + 1/R2 + 1/R3 + ...
Use as meny terms as there are resistors.
