  • I didn't get 2...is something wrong with me?

    pick a number:7

    x2=14

    +4=18

    /2=9

    I thought of 15

    15-9=6

    I got 6...did I do something wrong?

    Or is this whole trick crap?

    Just asking.

  • @ThePieceOCrap What I meant about the number you first thought of was the number you picked.

  • 0 doesn't work lol!

  • try reading the instructions carefully

  • Lol i used pi (3.141592654) and still ended up with two. And yea he never said it couldn't be a decimal.

  • @SHKmaster yeah even decimal i forgot to mention it

see all

  • picked 5 and got 3...

  • any number-x

    x*2

    2x+4

    (2x+4)/2=x+2

    x+2-x=2

    why the limitation of 0<x<11 ?

    

  • Any number here will work

  • @65AnimeCara65

    why 11-2? you have to subtract the number you have picked before, that was 9, not 2!!!!!!

  • I got 3!!!!

  • @rayven123456789 oh.....so the instructions shouls say "THE FIRST NUMBER U PICKED"

  • @cat9854xdeadx even if you take an imaginary number (e.g. i) it will work

  • @cat9854xdeadx even if you take an imaginary number (e.g. i) it will work
