First take 1000, then add 40 and then add 1000. Now add 30. Next add 1000 and then add 20. Then add 1000 and finally, add 10.
Sorry for the annoying way this OP is set up (with all of the spoiler boxes), but I’m curious over what answer people will get. Again, hit reply and post your answer BEFORE you read any other answers in here.
This works a lot better if you say it aloud to someone. When I say it aloud to people, hardly anyone gets it right. Maybe one in ten do (if that). Seriously. Try it out to someone sometime and chances are, they’ll say the wrong answer that’s in this topic twice (so far).
However I’ve had this topic on a board before and even then people get it wrong here and there in the replies.
