Since I am not a mathematician, but have a more solid tendency towards physics, I can give you some uses of zero from the point of view of theoretical physics.
Zero is used to define anything with which we can take a relative difference to define a function over space and time or any other coordinate you might choose to define your domain over. Confused?
Let me give you an example. In electrostatics, we use 0 to define the potential of a charge distribution at infinity and thus we can find the relative potential at any point in space. And from there we get potential energy and work done and all sorts of other things.
Maybe an example in chemistry would help too. When defining electrode potential, we can't define the electrode potential for a half cell because there is no current. So we assume the platinum hydrogen electrode to have 0 electrode potential and from there we can compare the potentials of all other cells.
These are just a few examples, but suffice it to say that 0 is a tool which helps us in defining a lot of things which can't be defined absolutely.
Maybe it will help you.....Good luck for your project.
Take care,
Ayerhs.

Zero has 2 main uses in the decimal number system. One is to represent the additive identity, a number that when added to anything else gives itself. The other is as a placeholder to allow numbers to be written conveniently as a sum of powers of 10 (1234 = 1*10# + 2*10^2 + 3*10^1 + 4*10^0). The importance of this is it makes calculation easier - imagine trying to learn how to multiply Roman numerals. With 0 you just leatn the 9x9 multiplication table and some simple algorithms and you can add, subtract, multiply, and divide anything.

One use is as the identity property for addition.
X + 0 = X

umm.i dont think it was "found" by indians..it is the lack of an actual value. it can be a place holder

zero was found by indians.
zero makes a vale to became greater.
it is not only a number it a sing of greek god.
