you cannot divide by 0 = a-b\n&#92;

zero divided by zero is not defined\none divided by zero is infinity\n\nIf you have a series like a_n/b_n whre both and b converge to zero as n goes to infinity, it might still have a limit, determined by what goes to zero faster a and b

Any number raised to the power of zero is 1. Why? Start with a simple problem: Divide one number raised to the power of n by the same number raised to the power of n. (In the example below, I use ** to mean "raised to the power." And I use the number 3 just as an illustration. It works with any number, and if you wanted to make this a general proof, you'd probably substitute "x" for the 3.)\n\n3**n / 3**n \n\nWe all know that any number divided by itself is 1, right? So 3**n divided by 3**n is 1.\n\nAnd to divide one number that has an exponent by the same number with an exponent, you simply subtract the exponents.\n\nSo:\n\n3**n / 3**n = 3**(n-n) = 3**0\n\nSo 3**n / 3**n equals 3**0\n\nAND we know 3**n / 3**n also equals 1.\n\nSo, 3**0 equals 1.\n\nHope this helps!

Do you mean "zero of a polynomial?" If so, then read on...\n\nA zero of a polynomial is the value or values of the variable (usually x) that cause the polynomial to equal zero.\n\nExample 1: The zero of the monomial 3*x is 0 because 3*0 is zero.\n\nExample 2: The binomial x + 2 has it's zero at x = -2 because if you substitute -2 in place of x, then you get \n---> -2 + 2 = 0.\nTherefore, -2 is the zero of the given binomial.\n\nExample 3: Find the zeros of the trinomial x^2 - x - 6. That is, solve x^2 - x - 6 = 0. If you factor the trinomial, then you get \n---> (x + 2)(x - 3) = 0. \nIn this problem there are two possibilities. Either \n---> x + 2 = 0  or  x - 3 = 0. \nSolving each gives x = -2 or x = 3. Therefore, the zeros of the given trinomial are -2 and 3. \n\nIf you substitute -2 into the given trinomial, then you have the following:\nx^2 - x - 6 \n= (-2)^2 - (-2) - 6 \n= 4 + 2 - 6\n= 6 - 6\n= 0 \n\nIf you substitute 3 into the given trinomial, then you have the following:\nx^2 - x - 6 \n= (3)^2 - (3) - 6 \n= 9 - 3 - 6\n= 6 - 6\n= 0 \n\nThere are no other values of x that will cause our given trinomial to equal zero.\n\nDefinitions\nA monomial is a polynomial with one term.\nA binomial is a polynomial with two terms.\nA trinomial is a polynomial with three terms.\nA polynomial with more than three terms is just called a polynomial.\n\nNote: If you graph a polynomial, then the graph will touch or cross the x-axis at the zeros of the polynomial. Zeros of a polynomial are also called solutions, roots, and, in some cases, x-intercepts.

I do not think you can.\nSo Bhaskara tried to solve the problem by writing n/0 = ∞. At first sight we might be tempted to believe that Bhaskara has it correct, but of course he does not. If this were true then 0 times ∞ must be equal to every number n, so all numbers are equal. The Indian mathematicians could not bring themselves to the point of admitting that one could not divide by zero. Bhaskara did correctly state other properties of zero, however, such as 02 = 0, and √0 = 0.

Zero. Look at the top have of that division problem.

The misconception is that dividing by zero produces infinity. However, if the number divided by zero is negative, the result would be negative infinity. Therefore, division by zero is undefined.\n\nHowever, it is possible to describe this in terms of limits. For example, as x -> 0, 1/x -> infinity. However, at no time is x = 0.

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

To quote dilbert: "Early Civilisations never had a concept of zero" (hey, you wanted it thorough right?) And they started the number system at one. .... Hmm, pretty much the panel cuts out... \nRemember, the ones and zeros are really the positive and negative polaritys on a magnetic disk. That is the key to your computer informations. Do not take a magnet to your computer.

OK, first off no one seemed to be able to answer the dividing by 0 and 1 issue correctly, so here goes...\n\nDivision by n is defined as multiplication by the multiplicative inverese of n.  The multiplicative inverse of n is defined as the number 1/n such that n*(1/n)=1.  Zero has no multiplicative inverse because 0 times anything is 0.  Therefore division by zero implies multiplication by a number that does not exist.  One does have a multiplicative inverse (1x1 = 1), so division by 1 is perfectly valid, although you are correct that the result is the number which was divided by 1.  It is exactly the same as multiplying by 1.\n\nNow on the area of a circle issue...\n\nYou seem to be trying to relate area to circumferance.  It's not hard.\nLet A = the area of the cirlce, c = the circumferance, and r = the radius.\nYou already know that A=(pi)r^2 and c=2(pi)r.\nSolve the second equation for r and get r=c/(2pi).\nNow substitute that into the first equation to get A=(pi)(c/(2pi))^2.\nThen simplify and you get A=(c^2)/(4pi).\n\nLike it or not, you can't get rid of the pi.  Pi is defined as the ratio of the diameter of a circle to its circumference, so it's going to be there no matter what.  When you say it's useless unless you know all the digits, this simply isn't true.  Depending on what you're doing, you can either get the pi's to cancel out, or you will be finding a decimal approximation of the area or circumference.  If the radius is a whole number, the area simply won't be (there may be a few values for which it will be, but most of the time it isn't), and any formula you come up with that says otherwise is incorrect.\n\nAs for the sphere question, I don't understand what you're asking.  Are you trying to equate area to volume?  They're not the same thing.  You can't find the area by sticking together infinitely thin slices as the slices have no height so you will never have a third dimension.  You might be able to do it using limits, but that's not going to be the kind of nice simple numbers you're looking for.  If you can explain what you meant, I might be able to do a bit better.

Infinity\n\nAddendum:\n\nI was astonished to see that the majority of answers are not converging on infinity, as I had learned in school. So I did a little more research. \n\nIt definitely remains as the mathematical definition that Z/0 = infinity for any non zero value of Z. However, as computers cannot process infinity, calculators etc., all show error or undefined. Modern applied mathematics are now teaching contexts where the result is defined and contexts where it should be considered undefined.\n\nAlthough its clear infinity is still the text book answer, it is also clear than in a practical sense infinity has no value and you still need to code around the case in your calculation software.\n\nLook below for many of the sites that discuss this.

Yes, zero is a number with a special property x + zero = x.\n\nIn most numeral systems, there is no zero symbol.\n\n0 is a digit who's name is zero.\n\n0 is not 'nothing'.  It is a number that can represent the cardanality of an empty set.\n\nThe greek capitol letter Phi (a circle with an up down line through it) is used to represent the 'empty set' or the set with nothing in it.

It's true.\nThe answer is indeed y = 0.\nYou can find this by dividing each side by -4.\n-4y = 0\n-4y/-4 = 0/-4\ny = 0\nRemember that zero divided by any nonzero number is always zero.
