Increasing-powers mode
When Increasing-powers mode is selected, polynomials will be listed so that the terms will have
increasing powers of the independent variable (which is the opposite to how polynomials are
normally written). [Default: unselected.]
Comment:
Who cares really?
Rigorous setting
When Rigorous mode is selected, any algebraic expression of the form |X|, i.e., the absolute value
of X, is not simplified to X. [Default: selected.]
Comment:
Your choice here really depends entirely on the problem at the time.
Simplify non-rational setting
When Simplify non-rational mode is selected, non-rational expressions will be automatically
simplified. [Default: selected.]
Comment:
When this mode is not selected an expression such as the
one shown right will not be simplified. When selected, it
simplifies to ¼. I suggest that this is generally more
desirable!

Changing the configuration can have a profound effect on the behavior
Before you play with these configurations too extensive
is suggested that you read carefully the relevant information in the
manual and/or the information in Renée de Graeve’s book mentioned
