Resistance in Series - add up all of the R values.
equivalent resistance of resistors in series :
R = R1 + R2 + R3 + ...
Resistance in Parallel - 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 +...

Series circuit. E=I (Res 1+Res 2 +Res 3...)
Parallel circuit E=I (1/Res 1 + 1/ Res 2+ 1/ Res 3 ...)
In a compound circuit, simplify the series Resistances into one large resistor and do the same with the resistors in parallel. Then use Ohm's law and compute for total Resistance.

If the resistors are connected one after the other, they are in series. If all the resistors are connected across a voltage source, they are in parallel. When the resistors are in series, the total resistance is the sum of all individual resistances. When the resistances are in parallel, the reciprocal of the total resistance is the sum of the reciprocals of all resistances.
Series : R = R1 + R2 + R3 + ...+ Rn
Parallel : 1/R = !/R1 + 1/R2 + 1/R3 + .....+ 1/Rn

question as asked is nonsense but this may help
for a series circuit just add up the individual values
eg 5 + 5 = 10
for parallel invert the resistance values , add up , then invert back
eg 5 II 5
1/5 + 1/5 = 2/5, invert = 5/2 = 2.5
alternatively use product/sum = 5x5 divided by 5+5
= 25/10 = 2.5

series circuits are added so you add individual resisters together to get a total sum i.e. 125ohm +235 ohm +234 ohm ... total and answer
parallel will have the same voltage in a resister bridge but not the same current value so in this case you need to 1/(1/R+1/R+1/R) R=ohms to get a total resistive value.
or for simplicity sake simply put parallel circuits have the same voltage and series circuits have the same current. little hint E/I x R

Resistance in series means the total resistance in a conductor where there is only one path for the electricity to flow. (R1 + R2 etc.) When there are two or more paths for the electrons to flow you use the other formula 1 over 1/R1 + 1/R2 etc.

Resistance in serires is added linearly:
R_1 + R_2 + R_3 = Total Resistance
Resistance in parallel is added as such:
1/R_1 + 1/R_2 + 1/R_3 = 1/Total R
