At first glance, the question seems simple Are there more doors or wheels? To begin to analyze this, we must first define what constitutes a door and what qualifies as a wheel. Doors can be found in homes, offices, vehicles, and public buildings. They serve as entrances, exits, and barriers for safety and privacy. A simple calculation of the number of doors in a typical house, for instance, can reveal that a modest home might have anywhere from a few to a dozen doors, including interior doors, exterior doors, and cupboard doors.

5. Check for Level Use a level to ensure that the door is aligned correctly. An unlevel door can cause excessive wear on the rollers and the track, leading to future misalignments. If necessary, make further adjustments to ensure the door is perfectly level.
