Why is 1 0 not a real number?
The short answer is that 0 has no multiplicative inverse, and any attempt to define a real number as the multiplicative inverse of 0 would result in the contradiction 0 = 1.
Does 0 over 1 exist?
Just say that it equals "undefined." In summary with all of this, we can say that zero over 1 equals zero. We can say that zero over zero equals "undefined." And of course, last but not least, that we're a lot of times faced with, is 1 divided by zero, which is still undefined.
Does 0 really exist?
The number 0 is the smallest nonnegative integer. The natural number following 0 is 1 and no natural number precedes 0.

Why is 1 divided by 0 infinity?
As much as we would like to have an answer for "what's 1 divided by 0?" it's sadly impossible to have an answer. The reason, in short, is that whatever we may answer, we will then have to agree that that answer times 0 equals to 1, and that cannot be true, because anything times 0 is 0.
How is 1 ∞ zero?
Infinity is not a real number and is only used as a representation for an extremely large real number. Dividing 1 by infinity is equal to zero. In general, any real number divided by infinity is zero, and the quotient of nonzero real numbers that divide infinity is infinity.
Is 0 0 an infinity?
In IEEE arithmetic, division of 0/0 or ∞/∞ results in NaN, but otherwise division always produces a well-defined result. Dividing any non-zero number by positive zero (+0) results in an infinity of the same sign as the dividend.
Is 0 a fake number?
The number 0 is at the center of the number line, so we know that 0 is a real number. Furthermore, 0 is a whole number, an integer, and a rational number. Since the real numbers include all of these types of numbers, we know that 0 is included in the set of real numbers, solidifying the fact that 0 is a real number.
Does infinity over 1 exist?
Infinity is a concept, not a number; therefore, the expression 1/infinity is actually undefined.
Is 0 nonexistent?
zeroes just like infinity, probable do not exist in the "real" world. There is not a single observed entity that has a no properties, by the very definition, if it did, it would be unobservable. The closest things to "zero" as we get is empty space, but quantum indeterminacy prohibits completely zero energy in space.
Does 1 0 go to infinity?
For example, 1/0 leads to an infinity that is different from an infinity that results from 2/0, and so on. We end up with an infinite number of infinities, and it doesn't look rosy for us at this point.
Can you prove 0 exists?
THERE IS NO SUCH THING AS '0'. Only infinity. Numbers are not linear(represented by a number line) but circular with infinity as a point. Number addition and subtraction are done in relation to infinity.
Does 0 exist in Z?
Z = (..., -3, -2, -1, 0, 1, 2, 3, ...} Integers are sometimes split into 3 subsets, Z+, Z- and 0. Z+ is the set of all positive integers (1, 2, 3, ...), while Z- is the set of all negative integers (..., -3, -2, -1). Zero is not included in either of these sets .
Why is 0 0 impossible?
One can argue that 0/0 is 0, because 0 divided by anything is 0. Another one can argue that 0/0 is 1, because anything divided by itself is 1. And that's exactly the problem! Whatever we say 0/0 equals to, we contradict one crucial property of numbers or another.
