What is required for two resistors to be in parallel? Do R2 and R3 meet those requirements? If so, they are in parallel?
Another easy to miss subtle point: What is the voltage difference across this resistor network?
Take your best shot at drawing a schematic and show it. Then we can give you feedback to figure out if and where you made a mistake.
This would certainly appear to match. To verify it, color each node a different color and then identify those nodes in the breadboard. If they all match up, then you are good.View attachment 140239
This is what i have drawn so far
