See below for an example. The units in this formula cancel out. Instead I observe this behavior (not just in this case, ALWAYS): The units just keep piling up to an unmanageable pile. That's why I gave up on including units entirely, I end up with 5% (of total screenspace for the entire result) for the numeric part and 95% for the bloated unit result.
How do I get Maple to process the units and not just carry them? I know it can do it, after all, sometimes it does. I just can't see the system.
