Lesson 1: The Basic Near-Numbers 

The learning goals for this video are as follows:

1. to be able to sketch and describe any basic near-number (finite, infinite, or constant);
2. to be able to recognize and distinguish any basic near-number(s) shown to you;
3. to be able to sketch slices of any basic near-number α—both the general picture slice_t α and the slice for any given t.

Further exploration:

• for a given slice of some near-number, use inequalities to express which real numbers x live in that slice (always remember: an inequality often serves as a symbolic description of some picture!).
