why 1\0 is infinity?

Answer 1

it's not infinity.. its undefined

Answer 2

Hi:

The reason you can divide any number by zero is because of what division is :

Repeated subtraction or Multiplication in reverse


For example :

9/3 = 3 Why

because :

9-3= 6 (1) : 6-3=3 : ( 2) 3-3= 0 (3) { (X) is the number of subtraction }

the number of subtraction is 3

So 3+3+3 = 9 or 3*3=9 so that 9/3=3. Okay with that out of the way. Let see what happen when you try to divided by zero:


10/0= ???

10-0=10 (1) ; 10-0= 10(2); 10-0=10 (3); 10-0=10 (4) .......infinity

the number of subtraction will go on forever So that it is undefined or infinite. Because there is no way zero can bring it down to a lower value than the orginal number ( Just think about it)

Now with multiplication you know that any number times zero is zero so that the number of solutions is infinite because any number can be the solution to it

Hope this answer your question.

Answer 3

1/0 is not infinity because infinity is not a number . But in 1/x , where x tends to zero then 1/x becomes larger and larger. Division by zero is undefined and one of the reasons is that 0 has no sign and hence the product will not have any known sign

Answer 4

It is some thing like if you have 50 apples and there are 10 people to get those apple equally then each will get 50/10 = 5 . So it is a matter of equality. When there is nobody , then 50/0 = infinity. It means each nobody will get infinite numbers of apple.

Answer 5

Because you can devide 1 to 0 and you will never finish with that!
But you know probably that -1/0 is also (- infinity)?
... just joking :0)

Answer 6

1/0 isn't defined as infinity in the math we are taught in school. This isn't because of some logical reasoning, it's simply a rule. In different maths, it can have a value, such as infinity.

Answer 7

This is the way why define our mathematics. But think of it like this:
divide 1 by 2 and you will get a number; divide 1 by 5 and you will get a smaler number; divide it by 100 and it will be even smaller. As you increase it, the result will get smaller and smaller. Eventually it will approach zero.
Now go the other way: divide 1 by 2 and you will get a number; divide 1 by 1 and you will get a larger number; divide it by 0.2 and it will get larger; as you make it smaller and smaller, your result will get larger and larger. In the end it will approach infinity

Answer 8

It is not infinite, it is undefined. Think of it this way, when we divide by 2 we take half of something. Divide by 3, we take a third of something. We divide by 0, we get an error. Because it is impossible to have 0 parts of a whole number.

Answer 9

1/0 is undefined not infinity.
infinity is a concept not a number.what will u do if u have to divide 1980 oranges to 0 persons?

Answer 10

Try the equation, x/y = z.
Whatever be the value of x, as the value of y decreases, the value of z increases. Hence, as the value of the denominator, here y, approaches zero, the value of fraction, here z, increases and reaches infinity.

Answer 11

limit of x>0 --> 0 of 1/x is +INF
limit of x<0 --> 0 of 1/x is -INF

1/0 is ridiculous.
