Nice to see another one coming from you Pop, you got me stumped. Keep em coming.

I thought it was going to be, 30 divided by 30. I think that's a better choice. Maybe you should send in anotha like that cuz i don't have enough pointz to do it myself! By the way, who else thinks we should demolish the point thing?
Oct 16, 2005

I'm with harrypotter on this one. i thought it was 30 divided by 30
Oct 16, 2005

I think it was made for you to think that it is 30 divided by 30. Nice trick
Oct 17, 2005

Yup me too, I thought it was 30/30 too.... tricky one !
Oct 17, 2005

Hmm... I know it's not the best teaser, but oh well! I still like it! (and whoever went to correct it, thanks! I hope it gets accepted)
Oct 17, 2005

Your welcome pop (I tried to....)

It was rejected, as all my corrections seem to be. Try to correct it yourself, if you say "My Teaser" they seem to always accept.....

Ohh well, good teaser pop

I liked it. Unlike the other people, It stumped me that it wasn't 30/30, but it was 30 seconds plus 30 seconds. I thought that was a tricky answer, which made the more obvious choice to easy. You understand? Anyways, I gave you a medium for hardness because it was a little hard. Great teaser!

I like it how you have it Pop! It is the trickyness that makes it a good teaser.

I liked this one, straight to the point, had to look at it a couple of times,But finally got it, Good Job!

I'm glad I wasn't the only one to think that the answer was 30/30. After I looked at the correct answer, I felt very silly.
Nov 25, 2005

I like this one. Also thought 30/30. Very nice job
Jan 29, 2006

couldn't 30/30 = 1 in fractions??
anyhoo, nice teaser thanks
Feb 01, 2006

Very nice
Feb 01, 2006

Am I the only one that had 30 minutes and 30 minutes = 1 hour?
Either way, I'm not 100% convinced this falls in the "trick" category.
Feb 05, 2006

Well... I guess minutes work, too... but that is still time!
Feb 11, 2006

Yeah, I had minutes too...

Great teaser!
Feb 12, 2006

I think there could be a lot of answers to this one 30 divided by 30 is 1, 30/30 as a fraction equals 1,and the time thing!!! i guesss thats y it is a trick !! good teaser !
Feb 20, 2006

Count me in the 30/30 group.
I would never have thought about time. I'm temporally impaired. Time is a stranger to me.
Mar 19, 2006

30+30=0 in time. 30 seconds + 30 seconds = 0 seconds (mod 60 seconds)
Mar 19, 2006

But 60 seconds is 1 (minute)
Mar 23, 2006

Great teaser...i'll use this one at home and see if others get it, lol...not sure if this is a "trick" question but still good job.
Oct 31, 2006

i thought 30/30 too
May 28, 2007

how is everyone thinking 30/30 when it clearly says 30 plus 30?

plus = +
Jul 01, 2008

It time, you could have also answered 30 minutes plus 30 minutes equals 1 hour...
30/30 would make sense if the question was "30 and 30" not 30 plus 30. Good trick!
Apr 30, 2009

I thought it was 30 minutes plus 30 minutes equal and hour
Aug 18, 2009

haha... I agree it could be 30 min PLUS 30 min = 1 hour....... When I first read it I just answered "never." It says when...
