Choose your favorite number, now divide this number by zero. What is the result of this operation?
The answer is undefined, but why?
Let me tell you the answer in this blog post.
The simple answer is, we don't have any predefined definition for this behavior, that's why undefined.
We'll look at why there is no answer to this problem.
let us take number 7 for our example,
now divide this number by 0,
7/1 = 7
Next, divide it by 0.5,
7/0.5 = 14
lets go for more smaller values near zero,
7/0.1 = 70
7/0.0001 = 70000.0
So you can see as we are going near zero, the values are getting larger and larger.
So now, let try the opposite with negative values.
7/-1 = -7
7/-0.5 = -70
7/-0.1 = -700
7/-0.0001 = -70000
here, values are getting smaller and smaller as we are going towards zero.
Due to this reason, mathematicians got confused and named this phenomenon as undefined i.e. not defined.
