Zero divided by zero what does it equal

0/0=

This is undefined, it could mean anything.

Anything times zero is zero right?

Let A be anything.

A*0 = 0

now divide both sides by zero

A = 0/0

see?

There is however something we can do using calculus to get closer to a real answer to this question.

The Limit as x --> 0 of x/x is 1.

It's undefined.
But if you take 0*x = 0 and divide it by zero to isolate x, you get x = 0/0. So 0/0 = all real numbers.
And if you gave it as a constant, c, and wrote it as c/x, as x approaches 0, the value of the expression approaches positive or negative infinity. If 0 is substituted for c, then it would make any number zero, making the expression 0/0 = 0

All division by zero is undefined,
but as we get close to the zero divisor,
in limits we go to infinity.

ex)
1 divided by a really small number
1 ÷ 1/100,000,000,000 = 1 * 100,000,000,000/1 = a really big number

Easy way to remember undefined is this. At least it worked for me. If a zero is ever under the line (division bar) it is undefined

under the line, undefined!

It's undefined.

Any other non-zero number divided by zero is infinity.

You cannot divide by zero.
