7 to 11
Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.
How do you change 7 to 11 without doing any math at all?
Answer
eleven=(seven-s)+el

| I thought it said "...not math at all" ?? OR did it not? I think if you add something it IS math, isn't it?!?! |

| How about you lay out 4 matches,like so-V11, which is roman numerals for seven. Then simply remove the V leaving 11..!!! |

| ok until a certain someone (cough)bmotts(cough) brought up a different subject, i thought that this was going a very nice direction. I like whoever said the toothpick thing, and the slurpee thing was quite clever. You know what, I'm not quite shure what i am trying to say so i will just stop talking now |

| I thought to wait four hours also, but your answer is good. I think you should change the l to a capital L though- it makes more sense. |

| It was a good but easy teaser, and the comment s about watching the clock for 4 hours were funny. Keep it up and don't worry about ANY CERTAIN IMMATURE PEOPLE! |

| That's wrong because 11 is spelled eleven, where as in your riddle, you have (seven-s)+l. If you did it that way, you'd have elven, and that's wrong! |

| I don't get it. u used math and you got the answer of leven.
JUST THE WAY I LIKE IT. NOT!!!! |

| You said by not using math yet you came up with the answer by -s and +l . Correct me if I am wrong, but isn't subtraction and addition still considered math? Your teaser is incorrect.

| hehehe while i was willing to ignore the fact that maths symbology was used to explain the answer, obviously others weren't.
i did however get that you should take the s off and put another e and an l in there (though the l looks strangely like a 1 on my puter) |

| So many negative comments! Although I do have to agree, math was used. I did like the toothpick answer. However, my answer was to take the top off of the seven and put it next to the other line, making essentially two 1's |

| That is letter math....so you ARE doing some math. |

| Erasing the top of the 7 and rewriting the line next to the 1 to make 11 is NOT math. It's called writing.
Interesting teaser... not my favorite. Sorry.

| people it isn't elven. its eleven. seven minus the s makes even. add el to the front and its eleven.
But that is math., |

| is technically math |

| I assume the correction added the e to make el at the end of the equation. |

| Technically wouldn't the adding and subtracting be doing math, even if no numbers are involved? |
