Left examples have the keyword "notso" on the OEBP.
We cannot expect to include all the fitting left examples on the OEBP here.
"Not so" Problems are closely related to "whole" Problems (left-BP509).
On the OEBP, the "not" side is conventionally the right side.
"Not so" Problems are typically narrow on on the left side (left-BP513) and not narrow on the right side (right-BP514). This will not be true in a "small enough" world where both sides are narrow. In these cases it is sometimes not clear which side is the more natural "not." |
