I was wondering what set up would I use on this particular section (18-23). It seems like a number line type of set up but I am having hard times breaking it down as such.

Appreciate the diagram, however can I get an explanation on how to use this to answer questions? I just don't see no concrete info, in game to base anything off. Thanks

can you expand on this explanation? I am confused on the set up and couldn't buy a answer while testing.
