why can you not divide by 0?

We say that division by zero is undefined, for it is not consistent with division by other numbers.\n\nHere's a little experiment for you to try on your calculator. Observe the output when you try the following set of calculations:\n       1/1\n       1/.1\n       1/.01\n       1/.001\n       1/.0001\n       1/.00001\n       etc... \n\nuntil your calculator can't go any further or you get tired. You should notice that the answers continue getting larger and larger. \nAnother way of thinking of it is to imagine filling a box with apples. Say a box can hold 100 apples. Now try filling it with apples that are half the size of these apples. You can put 200 in the box. Now imagine a special, magic apple that takes up no room at all. How many can you put in the box?\n\nWell, the answer is... there is no answer! That is why mathematicians refer to numbers that are divided by 0 as "undefined." Some people tend to think of them as being infinite, but this isn't exactly true. There simply is no answer.

b) Replace y with 0\n(100+x)^0 = 2*100^0\n1 = 2*1\n1 = 2\nThis implies that y cannot be zero.\nc) Replace x with 0.\n(100+0)^y = 2*100^y\n100^y = 2*100^y\n0 = 2*100^y - 100^y\n0 = 100^y\nThis is never true.\nThis implies that x cannot be zero.\na) The graph looks similar to the graph of y = 1/x

It may mean the computer is trying to divide by 0

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.

It isn't.  Zero divided by zero is a non-defined number.

Zero divided by any number (except zero) is zero.

since this limit is in a indeterminant form of 0/0 you can apply L'hospital's (sp?) rule\nwhich is taking the derivitive of the top and the derivitive of the bottom and evaluating the limit\n\nso this becomes [1/(1+x)]/1\nwhich is Lim x->0 1/(1+x) \n= 1/1 = 1\n\nedit:\nbah in that case im not sure...\nmaybe try a table of values and show that from each side of zero the limit approaches 1

The way you asked the question, you can't do it.  However, you can do something similar, and you don't always get infinity.  If you take a number, say 5, and divide it by (positive) numbers closer and closer to zero, you will get larger and larger numbers, and you can make the answer as large as you want by making the the denominator small enough.  For this problem you say that "the limit, as x approaches zero, of 5 divided x, is infinity."  You might say, 5 divided by zero is infinity for short, but that it isn't exactly correct.  \n\nNow here is another problem:  What is the limit of x divided by x as x approaches zero?  In this case, the answer is always 1 unless x is equal to zero, where it is undefined. The limit, therefore, is 1 , not infinity.\n\nA very important example.  If I am travelling 60 miles per hour, what is the limit, as the time  approaches zero, of (distance travelled in miles) divided (the time travelled in hours).  The limit is 60.  This kind of problem is the essence of differential calculus, which is important in just about every science, engineering and even social science field.

Division by zero is undefined, even if you divide zero into zero.\n\nhttp://en.wikipedia.org/wiki/Division_by_zero

Any non-zero number divided by a limit approaching 0 WILL go to infinity:  n/(lim->0) is inifinity so n/0 is infinity.\nBut 0/0 is UNDEFINED.

(a+b)(a-b)=b(a-b),\nhere you want divide both sides by a-b,\nbut this is not accepted,\nbecause a-b=0 (as you have assumed that a=b)\nDivision by 0 is not defined.\nDividing both sides by 0 is your mistake.

I too failed math but to me this is a logic question:\n0+0=0\nWhat else cloud it be?

Can't divide by a+b-c since it is zero.

Division by 0 is undefined. \n\nIf you divide 4 by 2, you get 2. Reverse the process: 2 multiplied by 2 gives you 4.\n\nThe reason you can't divide by 0 is because you can't multiply 0 by any other number and get a number besides 0.\n\n4 divided by 0 gives you "undefined." That would mean that "undefined" times 0 should equal 4. But that's silly.

The trick with "proofs" like these are generally an obscured division by zero. One of the lines seems to work, though when you divide to cancel out some factors, the quantity you're dividing by could/does equal zero. It's a trick and doesn't say anything substantial about mathematics.

u can't get a remainder only a decimal

My old math teacher showed me this.\n\nSince A=B, then A-B=0, and you can't divide by 0
