Exact meaning of infinity both as theoretical and mathematical concept.

Infinity means:-
1.Unlimited    OR   when we use this term in Mathematics as infinity-1 (to subtract 1 from infinity)
  then you can imagine it as to subtract an ANT from EARTH.

infinity means no limit. so we can't find the end point of infinity.

 Why infinity(*,/,+,-) with/by 10000000000000000
remains as it is.

Infinity is an hypothetical concept to which we consider to be, but actually can't find it.Because in actual it is not a place to which we can reach or area to which we can find.

In class 9th,10th,11th and 12th we encounter with the problems in Mathematics or Physics or even Chemistry which contains the concept of infinity or we need to find the answer at infinity or for infinite time,etc.Here we take infinity as a point(in physics as to find electric field at infinity or to bring a charge from infinity at electric field.) to which we imagine as a small point which is very far away but where it is or exactly what is the distance we don't know.

But when we *(multiply) infinity with some no. then also it results to infinity because after infinity we dont't know that what will be there or we haven't find a point greater than infinity.


Why 1/0 is equal to infinity.

1/0 = infinity.

as- consider an area or forest with 1Lakh trees and 5 men are there to cut 1 lakh trees.
here if we divide the work equally among them  then each of them will get 20,000 trees to cut as

1 lakh/5 = 20,000.

but when we want to cut 1lakh trees and we have no men to cut those trees then it means that

1lakh/0 = INFINITY.

because there is no man available to do work which means the work will not going to be finish or the time to finish this work will be infinity.

Here we know that work is not going to be completed but then also we can consider that this work will be finished till Infinity.
