    This is really interesting. It's kind of a brain teaser.

    Condition : You must do this in your head. Don't use paper to write out the problem.

    Take 1000 and add 40 to it. Now add another 1000.

    Now add 30. And another 1000.

    Now add 20. Now add another 1000. Now add 10.

    What is the total?

    Quote

    Did you get 5000? Most people do, but the correct answer is actually 4100. If you don't believe me, try using a calculator or writing it on paper.

    Thanks.

    Wow, I couldn't believe it. heh. It really is interesting how calculating it step by step in your head really makes you think its 5000.

    I also got it right, it was however quite interesting as I for a 1/100th second I did consider 5000 before ending on on 4100.

    I even watched the spoiler before I tried, I still got the wrong answer (

    Quote

    5000

    ).

    But I have no idea on how I got it wrong. If I take all the 1000s, then just add the smaller numbers it gives me the correct number, but not when I do them in the direction it's written

    because when you add the final 20 and 10 finally it makes you think that you have full thousand whereas you have only one houndred.
