WHAT?

hehe, according to your answer, you'd end up with "elven"

I said watch the clock for 4 hours (From 70 to 110)

Good one, but adding is math, isn't it?

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

i thought u couldn't use math?!?!

how bout you just change the 7 to an 11!!! then you didn't do ANY math!

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

I would have said go get a slurpee! [:p

I hope that you are never in a spelling bee!!!!

If there's one bad "elven" teaser, I haven't heard it!

If there's one bad "elven" teaser, then this is it!!

If there's one bad "elven" teaser, I've just commented on it.

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!

Thats just ridiculous, isn't plus 1 math, well it is in my school

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)

last i checked =&- were math and elven isnt eleven but thats just me

last i checked =&- were math and elven isnt eleven but thats just me

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

Huh, didn't get it

One time I bought a lion smoothie from 7 11 i like dog cages and severly hungy rhinos eating resteraunts in new zealand

Whatever

this is such a dumb teaser

how bout this: put the two 1s in 11 to make 7.

electric, that was my thought too! Snap!

Good teaser though, well done for trying. maybe better suited in the math section tho

Yeah, just erase the 7 and write an 11

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.,

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?
