Depends on the kind of circuit. If it has resistors in series, then yes, add up the resistance. If in parallel then
The total resistance of a set of resistors in parallel is found by adding up the reciprocals of the resistance values, and then taking the reciprocal of the total:
equivalent resistance of resistors in parallel: 1 / R = 1 / R1 + 1 / R2 + 1 / R3 +...

The circuit is series and parallel. You add the series resistors and use the formula 1 / Rtotal = 1 / Ra + 1 / Rb for the parallel resistors. When youu are done you will have the equivalent resistance.

The equivalent resistance of resistors in series equals the sum of the
individual resistances of the resistor. Equivalent Resistance for Resistors in Series R = RA +RB +Rc and The equivalent resistance of resistors in parallel equals the sum of the Equivalent Resistance for Resistors in Parallel R=1/R1+1/R2+1/R3.

You can only add resistance if it is in series (one after the other). If the resistance is in parallel ,resistors with common circuit input and output,then the formula is (1/R1+ 1/R2= 1/RT, RT= total resistance).

It depends on the kind of circuit. If it's in series, yes you add it up. If it's in parallel, then 1/Re=1/# + 2/#...then there's more steps.

If the resistance is a series connection the Total resistance is the sum of the individual resistance; Rt = R1 + R2.
If the resistance is parallel then the total resistance is the product of the resistance divided by the sum; Rt = R1*R2/(R1 + R2)

If the resistance are connected in sieres we can find the equivalents by summation all resistances to gathers ..... R1+R2+R3............+Rn...
If the resistance are connected in parallel we can use spatial case to find the equivalent resistance
(R1*R2)/(R1+R2)
