Question

What would be the answer if we divide 0/0 ?

Answer 1

`0/0` is undefined.

Explanation:

`0/0` is undefined. The expression in and of itself comes into conflict with two facts of arithmetic: any number divided by itself is equal to one , and zero divided by any number is equal to zero . When we have both of these cases together, as in the case of `0/0`, we say it is undefined.

`0/0` is also sometimes called indeterminate form.

Answer 2

Ignore this one

Answer 3

Ignore this

Answer 4

Undefined

Explanation:

Now, instead of just acccepting this, let's try something.

Let's make `x=0/0`

Multiply both sides by 0.

`=>0x=0`

No matter the value of `x`, we always get 0 equal to zero. This means that `0/0` equals any number if it is defined!

Now, you may hear someone saying that `0/0=0` because `lim_(x->0)0/x=0`(you don't have to know this right now.)

But if you hear someone saying that, tell them this:

A limit does not mean the value is defined nor continuous. We are simply getting closer and closer to zero as `x` gets closer and closer to 0. (Sounds fancy, doesn't it?)

Just remember that when you start taking your calculus course, you will learn that `0/0` is called an indeterminate form(it doesn't have an exact value, yet there is a specific answer for a specific problem)
