Neither.\n0/0 is indeterminate, or undefined.

Decimal is the normal way to write numbers: .00002\nScientific notation is 2x10^-5\nTo do this just move the decimal over to the right (-) an count the number of 0's you pass and put 10 to that power.  If you move the decimal to the left then the power is positive.\n\nWhy do scientist do this?  In our solar system there are some very big numbers like 360,000,000,000,000.  It is easier to just write 3.6x10^14.  There are also numbers that are very small such as in atoms.  Hope this helps.

The rule is that when you're writing numbers you may use a hyphen after the tens place as necessary. And you only do it then if there is something IN the tens space to begin with, and something other than zero in the ones space.  'One hundred twenty-two', 'seventy-four' and 'five hunded thousand four hundred fifty-two' are examples. Also, if the numbers are below twenty, you won't hyphenate, as they names of the numbers are all one word in that case,ie one hundred twelve. Remember that you never use the word "and" unless you have encountered a decimal or fraction. I know you didn't ask that, but it seemed relevant. So, it's not one hundred and twelve, but one hundred twelve. Not two hundred and thirty-four, but two hundred thirty-four:)

Zero is in the Hundreds position. \n\nTwo is in the Thousands, \nOne is in the Tens position,\nNine is in the Ones position.\n\nOnce you move to the right of the decimal, it is:\n\nFour in the Tenths position,\nSix  in the Hundredths position,\nand Three is in the Thousandths position.

The symbol _ is called the underscore. You can type it by the combination Shift and - key.

the roman numerals are the same in any language:\n1- I\n2- II\n3- III\n4- IV\n5- V\n6- VI\n7- VII\n8- VIII\n9- IX\n10- X\n20- XX\n50- L\n100- C\n500- D\n1000- M\n2006- MMVI\netc.

You should use scientific notation to describe this number. Correctly expressed, this number is 1*10^n where n is the number of zeros you typed. (I don't know how many zeros follow the ...)

Use the digits unless it's the first word of a sentence.  You should never start a sentence with a numeral, but otherwise the general rule is you should only write out numbers smaller than ten (I usually write out other numbers too, though).  Also, don't write out numbers that have units attached even if they're smaller than ten.

MCMXLV\n\nM = 1000\nC = 100\nL = 50\nX = 10\nV = 5\n\nThe roman convention is:\nstart with the largest number that can be represented standalone. then the next number that can be formed by a minimun number of subtractions\nHence \nM = 1000\nCM = 900\nXC = 40\nV = 5\n\nRead more here: http://en.wikipedia.org/wiki/Roman_numerals

VERY GOOD Question!!!\nI don't know, but i never thought abou it either.\n\nwell if you only need to write 0 i guess you don't write anything. and for like 10 you just write an x so i guess there is not a zero because you don't really need it.\n\ni hope i was help!

0 as a number\n\n0 is the integer that precedes the positive 1, and follows −1. Zero first appeared as a number in Brahmagupta's work dated to 628. Prior to that Babylonians used a space marker that played one of the functions of zero. Babylonians did not have a special symbol for zero. In most (if not all) numerical systems, 0 was identified before the idea of 'negative integers' was accepted.\n\nZero is an integer which quantifies a count or an amount of null size; that is, if the number of your brothers is zero, that means the same thing as having no brothers, and if something has a weight of zero, it has no weight. If the difference between the number of pieces in two piles is zero, it means the two piles have an equal number of pieces. Before counting starts, the result can be assumed to be zero; that is the number of items counted before you count the first item and counting the first item brings the result to one. And if there are no items to be counted, zero remains the final result.\n\nWhile mathematicians all accept zero as a number, some others would say that zero is not a number, arguing one cannot have zero of something. Others hold that if you have zero dollars in your bank account, you have a specific quantity of money in your account, namely none. It is that latter view which is accepted by mathematicians and most others.\n\nAlmost all historians omit the year zero from the proleptic Gregorian and Julian calendars, but astronomers include it in these same calendars. However, the phrase Year Zero may be used to describe any event considered so significant that it virtually starts a new time reckoning.\n\n\n\n0 as a numeral\n\nThe modern numeral 0 is normally written as a circle or (rounded) rectangle.\n\nOn the seven-segment displays of calculators, watches, etc., 0 is usually written with six line segments, though on some historical calculator models it was written with four line segments. This variant glyph has not caught on.\n\nEarly Europeans hesitated to consider zero as a numeral or number. Leonardo of Pisa or Fibonacci says the following in 1202 AD when the Indian number system arrived in Europe.\n\n"After my father's appointment by his homeland as state official in the customs house of Bugia for the Pisan merchants who thronged to it, he took charge; and in view of its future usefulness and convenience, had me in my boyhood come to him and there wanted me to devote myself to and be instructed in the study of calculation for some days. \nThere, following my introduction, as a consequence of marvelous instruction in the art, to the nine digits of the Hindus, the knowledge of the art very much appealed to me before all others, and for it I realized that all its aspects were studied in Egypt, Syria, Greece, Sicily, and Provence, with their varying methods; and at these places thereafter, while on business.\n\nI pursued my study in depth and learned the give-and-take of disputation. But all this even, and the algorism, as well as the art of Pythagoras, I considered as almost a mistake in respect to the method of the Hindus. (Modus Indorum). Therefore, embracing more stringently that method of the Hindus, and taking stricter pains in its study, while adding certain things from my own understanding and inserting also certain things from the niceties of Euclid's geometric art. I have striven to compose this book in its entirety as understandably as I could, dividing it into fifteen chapters.\n\nAlmost everything which I have introduced I have displayed with exact proof, in order that those further seeking this knowledge, with its pre-eminent method, might be instructed, and further, in order that the Latin people might not be discovered to be without it, as they have been up to now. If I have perchance omitted anything more or less proper or necessary, I beg indulgence, since there is no one who is blameless and utterly provident in all things."\n\nLeonardo of Pisa \nHere Leonardo
