Only create the most minimal immediate #1

All operations should produce the most minimal immediate representation. Which is to say:

We should not have Sum with only one term (could be just a term).
We should not have Ratio that can reduce to a Sum or Term
- x + y / 1 => x + y (sum)
- 2x^2 / x => 2x (term)
- (x + y) / (x + y) => 1 (term)

Setup some test coverage that enforces this invariant.
