Deleting Variables and Equations

Each equation in the Solver list uses calculator memory to store 1) itself,
and 2) its variables.
Deleting a variable is quite different from clearing it:
Clearing a variable sets it to zero; the variable retains its storage
location in memory. This does not save memory space.
Deleting a variable erases its value and its storage location. This is a
way to save memory space. If a variable is shared, its value is lost to
all equations that share it. The memory space for a deleted variable is
re-created the next time you use that equation.
An equation that has not been verified (
