Concept of Zero is incomplete!

The Concept of Zero is incomplete, in that, it shows only the final result, but doesnt show what all went into making that zero.

For eg, if the cash flow for a company be:
Costs = Currency 100
Revenues = Currency 100
Net Result = Currency 0
then, although the net result is 0, on analysis we can see that the company did a lot of things over time, made products, sold them, covered costs, etc etc. The 0 doesnt convey all this by itself.

To know the entity, you have got to see the flow of events, rather than basing your judgement on the final result.

The same goes for a student who attempted a great many questions in a competitive test with negative marking, whose positives balanced off with the negatives. You would know more about the student only by evaluating the kind of questions he/she answered.

Well, the same holds for any X - Y = 0... How would '0' tell the story that there was once an 'X' and a 'Y'?

Ending the post with all due respect to the ancient civilisations that discovered the concept of Zero.
