Wanna bet?
prove me wrong.

Commas are NOT part of the decimal, and in fact are totally optional.
In China, they group their decimals every 4 digits instead of every three.
It's only there to make it easy to read.

Turn in that answer at most high schools and nearly all college math or science classes and your teacher would mark it 'wrong' simply for being incorrectly expressed.

Make sure it's worthless, and make sure HE pays the shipping.

"You're quite right, but then he said this"

Yes, but I did not check back until after it had already been answered. So at that point, there was no point.

I remember this question. There was an extra part to it, how tall would the piece of paper be when folded 50 times?

Maybe where you went to school, but not where I did nor where most do.

From my folks, one who was an award-winning high school math teacher for 35 years, the other a mechanical engineer whose designs orbited Earth.

simple math.

If the paper is .004" thick, folded that many times, it will stand over 71,079,539 miles high.

That enough to circle the earth more than 2854 times.

I didn't believe it either, so my brain read that number as 71 thousand, not 71 million.

or if Dood never has seen Snow I could send him a box of Snow (in a month or so)

I will let you guys decide

We typically get around 70-80 inches of snow annually in this part of Wisconsin, but snow in excess of 100 inches happens every couple years.

I'll take the picture of Nixon.

Each teensy tiny square is only 220 x 220 atoms in size.

(of course that is not considering the edges of the folds etc.)

I was going to ask that, if you started with a 10x10" piece of paper, folded in half 50 times what would the surface area now be? Gotta be AWFULLY small.

Mikado Logo 400, hopefully ready by spring.

Mythbusters folded a piece of paper that took up nearly the entire floor space of an aircraft hangar (I think it was for the Space Shuttle).

That piece of paper got small pretty quick.

Why has everyone assumed it had to be folded in half? The original question says nothing about it be half.

I not sure what you mean by bent. I was think about folding it like a fan or an accordion.

Layers are layers (although the math changes a bit) -- just ask any cake.
