By Jove! I just dropped my seventh calculator, and now it's telling me that a circle with an area of nothing has radius 3. You know that:

• The calculator calculates perfectly well
• The calculator's display isn't broken
• The calculator's buttons work properly
• "Nothing" isn't , by Jove!
• π is not 0
• I am looking at the calculator display as I normally would (not rotated or reflected in any fashion)
• The calculator is not in an error state (e.g. caused by division by zero, syntax errors)

How could this happen?

Hint:

The first thing you're looking for means "nothing"

Hint #2:

The first thing you're looking for is less than 5 letters long
