Schematic interpretation, where to put resister? I'm new to schematics, trying to figure out where to put a resistor (no  instructions other than the schematic)

I'm told I need:
10K variable Resistor x 1, 4.7K Resistor x 1, 100 Resistor x 1

But I only see where to put the 10k resistor (I added a blue circle around the 10k). Can someone show me (describe, illustrate) where to put the others?

And where there's the triangles for +5V or AGND, do I put something there (purple circles)??

Thanks!

Here is a link from the project I'm trying to build

Neither are shown in that schematic, as described in the text.

Calibration Circuit: The weight calibration circuit is shown in figure 2. [...]

Note: Cathode and Anode pin of LCD (pin 15 and pin 16) is not shown in circuit diagram. Connect +5 volt to pin 15 with current limiting resistor (generally 100-ohm) and pin 16 of LCD to ground.
