Consider the equation 0 times x = 0.
This is true for every number x.
Divide both sides by 0; we get x = 0/0.
So zero divided by zero could be any number at all; it could be -42, or 273.15, or anything else.
If we try to pick one value for 0/0, we will eventually get into trouble.
Examples:
Say 0/0 = 1 = 1/1.
Multiply the numerator of both sides by 3. Then
(3 times 0)/0 = (3 times 1)/1.
Therefore 0/0 = 3.
Since 0/0 = 1, we get 1 = 3, which we really don't want, as all of our mathematics will become useless.
Say 0/0 = 0.
Then 0/0 = 0/1.
Turn both fractions upside down. We get
0/0 = 1/0, but since 0/0 = 0, we get
0 = 1/0.
Multiplying both sides by 0 gives
0 times 0 = 1,
so 0 = 1, which we don't want either.
The best thing to do is not to give 0/0 any value; we say 0/0 is undefined. Also we take x/0 to be undefined for every number x.

One divided by zero is an undefined operation, which leads to contradictions and nonsense.For this reason, division by zero is forbidden in arithmetic.

A dur negative 1 ,0 does nothing when dividing
Zero and one - either on or off.
A prime number is one that has only 2 factors, itself and one. A composite number is one that can be written as the product of two numbers that are not itself. By these definitions, 1 and 0 fail to be either composite or prime. 1 can only be divided by one, so it does not have the 2 necessary factors to be prime or the multiple required to be composite. 0 on the other hand can be divided evenly by every number, but no two numbers that are not 0 can be multiplied to get a product of 0.
