Hard?!? Mathematics One

Using two digits and one mathematical symbol, what is the largest number you can make.

9^9 = 387,420,489

nope way larger

I should include that exponents don't count as the mathematical symbol.

hmmmmmm, well how about infinite: 9/0

Thats not the answer I'm looking for. It follows the standard math and I know that division by zero is undefined. If you need a hint, say so

ok, one more try... You want a LARGE number? How about 4/9 = .44444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444444

I assume this is not right either, so let's give it a few days before you drop any more hints and see if someone else can answer.

thanks for the riddle!

Use two digits you say? How about if i use 9 and 8....

(999999999999999999999999999999999999999999999999999999 X 999999999999999999999999999999999999999999999999999998)

Just trying to rack up some wrong answers here : )

Lol ok ill put it this way..
What is the largest value of an expression using two 9s and one mathematical symbol?
the value is too large to figure out.. so just give me the expression

Ok here is a hint:
The mathematical symbol is the twist on this one.
The symbol can be made using one straight line and one dot

99!

9^9!

Some-g is right.... If you've taken calc, then you know that

x/0 = lim(a=>0)(x/a) = infinity. Weather you like it or not.

After you changed your riddle, 9^(9!) or (9^9)! is the largest I can think of.

Uplink_Agent · Posted: Wed Nov 15, 2006 2:47 am Post subject:

Exclude Limit Theory...

and the anwer is (9^9)! so you are correct.

Just for info... 9^(9!)= some number with roughly 362,000 digits and
(9^9)!= roughly some number with 2 million digits...

somebody got it NICE WORK!

when you said "I should include that exponents don't count as the mathematical symbol," I thought you meant exponent wasn't in the answer... oops

glad this got answered... of course infinity is still bigger : )

lol, I should have qualify that the number is to be defined.

99infinity

after all, there is no number larger than infinity.

Yes the word infinity is only really big because somebody made it to be that way in math, in reality it is infinite and thus, undefined.

Besides, infinity is not a number, it is a concept.

6!8 looks like "big" when flipped up side down.
i forgot what 9! meant. is it 9X8X7X6X5X4X3X2X1?

I have one:

A horse travels the same distance every day.
Now, two of its legs travel 30 miles each day and the other two legs travel nearly 31 miles.
It would seem that two of the horse's legs must be one mile ahead of the other two legs, but of course this can't be true.
Since the horse is normal, how is this situation possible?

Unclever title · Posted: Sun Feb 11, 2007 12:58 am Post subject:

Normal meaning not a mile long? Or normal meaning that its legs are all the same size, Cause I was goint to say that two of its are longer than the other two.

Depends on your perception of "nearly."

Like I could say 1.9 is nearly 2 but 1.8 is not,
But someone esle could say 1.8 is nearly 2.
Get it?

The horse goes in a circle all day.. So the two legs on the outside make a larger circle each rotation, therefore travelling farther.

the horse bucks up on its back legs often, making its front legs travel a little more Razz

OR

the horse does fail jumps and is totally slanted during the process, making one set of legs travel a little more

btw, you can't actually say 9/0 is infinity because the proper term is that 9/x approaches infinity as x approaches zero, but on x=0 the function is undefined.
