## What is negative infinity?

Negative infinity is the opposite of (positive) infinity, or just negative numbers going on forever.

## Is 0 possible?

In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 00 is also undefined; when it is the form of a limit, it is an indeterminate form.

## Is there a negative infinity?

Infinity means different things in different contexts. … You can’t have a set with negative infinity numbers in it. You can’t even have a set with negative one numbers in it. Infinity added to the biggest negative number you can think of (or minus the biggest conceivable positive number) is still infinity.

## Is negative zero the same as positive zero?

Signed zero is zero with an associated sign. … However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero), regarded as equal by the numerical comparison operations but with possible different behaviors in particular operations.

## Is 0 positive a rare blood type?

O positive is the most common blood type as around 35% of our blood donors have it. The second most common blood type is A positive (30%), while AB negative (1%) is the rarest.

## What are the 3 rarest blood types?

## Is 0 a non negative number?

A non negative integer is an integer that that is either positive or zero. It’s the union of the natural numbers and the number zero. Sometimes it is referred to as Z*, and it can be defined as the as the set {0,1,2,3,…,}. Z, the set of integers, is defined as {…,-3,-2,-1,0,1,2,3,…}.

## What is the opposite of 0 in math?

The opposite of zero is negative zero. … Zero cannot have an opposite because it cannot be positive or negative.

## Why is O negative so rare?

People with O negative blood often wonder how rare their blood is since it is always in demand by hospitals and blood centers. … However, the rarest blood type in the world is Rh-null, which is so rare most of us have never heard of it.
