Having co-workers borrow your calculator once in a while may not be an issue, but when people start asking you for it every hour, the “Wrongulator” just might be what you need. This gadget is guaranteed to be wrong 100% of the time, meaning 1+1 = 3. It’s available now, priced at $8.12 from Red5.

The Wrongulator may look like a typical solar LCD calculator, but it’s designed to drive its users batty, by replacing all proper mathematical logic with complete and utter rubbish, providing brilliant answers like “10 + 5 = 10”.
