Newbie question about building from schematic on a breadboard

I'm unsure of how to connect r3 to vb on the breadboard   

I'm so sorry I forgot the schematic. My minds all over the place

R3 is connected to the junction of R8 & R9, a voltage divider, that point should read half the supply voltage. You could just plug the one end of r3 into the common strip of r8 & r9 or run a jumper from the r8/9 strip to the strip the free end of r3 is plugged into. A quick scan says pin 3 of the IC also needs to be connected to the r8/9 node.

Perfect thank you so much for all your help. I've seen it before on schematic's before but was always building from vero so never really figured out anything to be honest except how to assemble the board/wiring.  It's a step up from ordering a kit but still not great for trying to learn what everything does and how it works.  I find IMO breadboarding should be one of the first things anyone does
