what is the largest number u can write using only 2 digits( use any mathetical operation)?

Well, they used only one digit, which is 9.  Mine is\n(((...(((12!)!)!)!...!)!)! \n\n= infinity\n\n^_^

actually teh biggest number is infinity, and it isnt a defined value, it just embodies very very large numbers, therefore infinity and infinity^2 are actually the same number...pretty neat huh\n\nhope this helps!!

Since 2p22>222 then\n\n  2p(2p22)  is the greatest number\n\n\nMy calculator could not handle that high a number.\nSo I figured , using an inductive method, that the result\nis a 1 followed by 1,200,000 zeros.\n\n\nAnyone care to confirm or contradict.\n\nHere's how\n\n2p4,000,000=10p(x)\nx=4mil(log2)= 1.2 mil

8\ntake away o from top and you're left with o on bottom - half - nothing\nor i guess 10 could work, too (or any double digit ending in 0) take away the first number and you're left with 0

In decimal form the number 9^9^9^9^9^9 is so large that if every atom on the planet was to represent a digit we still wouldn't have enough room to represent the number.\n\nIn other words, Yahoo definitely doesn't have enough disk space to represent the number you're interested in.

In your case use your fingers bye the way 2+2 = 4

The biggest first number is 9.  You won't find a single digit larger than it.

not sure--The first one million digits of π and 1/π are available from Project Gutenberg (see external links below). The current record (December 2002) by Yasumasa Kanada of Tokyo University stands at 1,241,100,000,000 digits, which were computed in September 2002 on a 64-node Hitachi supercomputer with 1 terabyte of main memory, which carries out 2 trillion operations per second, nearly twice as many as the computer used for the previous record (206 billion digits). http://en.wikipedia.org/wiki/Pi still not sure-2002 was 4 years ago there maybe a larger number. http://directory.google.com/Top/Science/Math/Recreations/Specific_Numbers/Pi/Digits/

Hi,\n\n1) Start\n2) Get the first digit\n3) Compare with next  \nif ) 1 is larger go to next\nif) next is larger pick it and compare to next\n4)You have found the largest digit,\n5) find second largest in the same way\n6) Repeat till every digit is used

psbhowmick, 99 is divisible by 9, but 199 is not. You can't find the remainder simply by looking at the last 2 digits. For instance, the remainder of 22654785/19 is 2, not 9 as you suggest.\n\nDividing by 19, hmmm... the only shortcut I can think of is to use the mod function on your calcutor. Sorry.

You can do this by hand.\nCall your number x.\nWrite the binary digits of x as b_i :\nx = sum_n=0_n=N b_n.2^n\n\nThe algorithm is simple: compare your number x to the largest power of two (2^N), subtract if necessary, and decrease n until finished (n=0).\n\nStart with n=N , the largest integer such that X >=2^n\nIf x >= 2^n, then {\n b_n = 1;\n x = x-2^n;\n n = n-1; \n} else {\n b_n 0;\n}\n\nThe above is pseudocode, you could do it in C, PERL, Python, Java etc.\n\nSo: x= 121 = 64+57=(64+32)+25=(64+32+16)+9\n=(64+32+16+8)+1 =64+32+16+8+0+0+1\n\nThus 121 (base 10) = 1111001 (base 2)

There is no largest number, as one can simply define a new number to be strictly larger than it. There is a largest named number, http://www.math.toronto.edu/mathnet/questionCorner/largestnumber.html , and largest used number http://www-users.cs.york.ac.uk/susan/cyc/g/graham.htm .

It's just like the decimal system, only based on the number 2 instead of the number 10..........\n\n1  10  100  1000  10000  100000  1000000  etc... - Decimal\n\n1  2  4  8  16  32  64  128  256  512  1024  etc.. - Binary

Two hundred quattuordecillions\n\nCan be written using scientific notation as 2.0 x 10^47

I give up,what?They don't even make a calculator that will register that many digits and I sure don't want to figure it manually.I'm sure there are a lot of numbers that when multiplied would equal a 400 digit number.400 is only a 3 digit number.

The largest number that has a commonly-known specific name is a "googleplex", which is a 1 followed by a googol zeros, where a "googol" is  (a 1 followed by 100 zeros). \n\nHowever, there would be nothing stopping you from giving a special name to a still larger number (such as a googleplex plus 1), and then that would become the largest named number once the term became commonly known. \n\nIn summary, then: the mathematical question "what is the highest possible number" has no answer, because there is no such thing. But the sociological question "what is the largest number that anyone has ever decided to give a specific name to, a name which has become commonly known" is, for now, a "googleplex" (until someone decides to coin a phrase for a still larger number and it catches on and becomes commonly known).
