# Does 0 divide every number?

## Does 0 divide every number?

We know that 0 divided by any number is 0, but we also know that any number divided by 0 is undefined.

## Is anything divided by itself 0?

(Multiplication is an inverse operation of division.) Any number, except zero, divided by itself is 1. Any number divided by 1 is that number. Zero divided by any other number is zero.

Why can’t kids divide by zero?

The reason that the result of a division by zero is undefined is the fact that any attempt at a definition leads to a contradiction. r*0=a. (1) But r*0=0 for all numbers r, and so unless a=0 there is no solution of equation (1).

What is any number divided by zero equal to?

ZERO DIVIDED by zero is quite indeterminate. For if A is B times C, then A divided by B is C. But zero is equal to zero times any number whatever. Therefore zero divided by zero is any number whatever. Ivor Etherington, Easdale, Argyll.

### What happens if you divide by zero?

In ordinary arithmetic, the expression has no meaning, as there is no number which, 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 0/0 is also undefined; when it is the form of a limit, it is an indeterminate form.

### Why is zero not a number?

Since 0 is not a number, zero cannot be a word either, since 0 and zero correspond to the same thing—nothing. If something is a number or a word then it is something and cannot be nothing, which contradicts the obvious fact that 0 is nothing.

What is a number less than 0 called?

Well those numbers are called negative numbers. From the number line , 0 is present at the centre; the numbers towards right are called positive numbers while those towards left are called negative numbers. Both positive and negative numbers constitute integers while the same along with decimals are called real numbers.
