Or start at the left side and break the circuit into equivalent sub-circuits by redrawing the remaining resistor layout. Whichever you understand better.

You have five 10Ω resistors.

Begin by labeling each resistor, e.g. R1-R5.
Then we can discuss resistors one at a time.

Find two resistors in series and calculate the equivalent resistance.
Find two resistors in parallel and calculate the equivalent resistance.

R1 and R2 above are in parallel.
R3 and R4 are in series.

R4+R5 then R1, R2, and R4-5 are in parallel, but what about R2?
One step at a time.

Find two resistors in series. Calculate the equivalent resistance. Redraw the circuit. Give the equivalent resistor a new name.

The find two more resistors that can be combined because they are either in series or parallel.

Redraw the circuit after each step.
