Trick of the mind

[Twisted Sanity]

Okay, I'll show you a series of numbers. Add them up, one after the other. But do it in your head, not on paper or with a calculator. Add the numbers as you scroll down, and try not to dawdle. Saying the answers out loud may also help Lets see if your mind is tricked as easily as mine was. (sorry for the vertical stretch mods, but it's necessary.)

Is your answer 5000, or 4100? If it's 5000, you're wrong The correct answer is in fact, 4100, but most people end up thinking that the answer is 5000. It's a strange thing, and I forgot why it happened, but hey, there you go.

[Kittie]

Whoa. I got 5000 O_O Thats so weird.

[WIS]

Huh, I got 4100...

I'm going to ask a couple of friends to do the same thing and see if they get 5000.

[Alex]

I've seen this before... I got 4100

[kiay]

I got 5,000 Wow, I'm so stupid, how could I make a mistake like that!

[Paul]

5k here too.

[Twizzler0171]

5k here, and I had read this without actually doing this an hour or so ago.

I is smart.

[Shifty]

Thats really wierd x__X
I'v seen it before, but even now, only when I do it on paper it comes out right, and when I do it in my head it doesn't o_0

[843]

I got 4100... how the heck do you get 5k anyway?

[Twizzler0171]

Oh! I think I just figured out why we get 5000 instead of 4100.

With all the >>>> making all the numbers seperated, and the thousands in odd places, when we reach 100, instead of counting it as 100, we make it a thousand in our heads. Or something.

[Qanda]

4100. I paid extra care not to make any mistakes, expecting a trick of some sort.

[Pokemon Kid]

4100.

I'm a mathimatician.

[Messs17]

I got 4100

[Shifty]

Oh nooow I see it....
When we reach 4,090, and it says add 10 more, somehow we get to 5000...

I can't belive I fell for that.

[sirclucky]

I got 4200-but I was working base 5
