Making User-Defined Transformations
If the built-in Rules transformations do not rearrange an algebraic
in the form you want, you can make your own transformations. A
“custom” transformation replaces occurrences of a pattern with a new
pattern. The pattern can be specific or it can contain “wildcards” that
match any subexpression and that you can reinsert in the replacement.
You’re informed whether or not a replacement was made.
