Not so much an "I used to believe" but...
When I was in 2nd or 3rd Grade, my parents made sure I knew my multiplication tables up to 12x12 (or I wouldn't get to go out and play). We hadn't yet been taught this in school, but I darn well made sure I had them memorised, as summer was soon coming around.
One day on the playground, I ended up in a fistfight with another classmate, as we got into an argument about 2x2. His stance was: "There is NO way 2x2 can equal 4, as 2+2 equals 4. Multiplication is different than addition, so you are lying!"
I'm not sure how it escalated to blows, but needless to say, the Assistant Principle could barely contain her mirth after we were pulled into her office.
