AI Thread Summary
Zero is a fundamental concept in mathematics, serving as the additive identity that leaves other numbers unchanged when added. It plays a crucial role in various mathematical theories and operations, including calculus and the definition of negative numbers. The discussion highlights the paradox of zero being perceived as "nothing" yet being essential for understanding and solving mathematical problems. Despite its challenges, the presence of zero is necessary to maintain the integrity of numerical systems. Overall, zero's significance extends beyond its value, influencing numerous mathematical concepts and applications.

Is zero anything or something then zero shouldn't be there?
For a nothing number it still causes us lot of trouble. Any takers?

I read a theory on the zero which kinda made sense.

Zero is the number that, when added to any other number, leaves that other number unchanged.

I'm not really sure what your question is...
 
it's also what you have when you have one apple, and then someone takes it away.

Zero also represents an empty digit in numbers that are more than a single digit

Can u tell us about it please ?
Thanks !
 
If zero causes us a lot of trouble, then it would cause us far more trouble if it wasn't here. Alot of mathematical concepts are dependent on a meaningful figure called zero. Calculus, far example...
 
Zero is the additive identity. If it was not there then how could you define the negative numbers (as opposed to being the additive inverse of positive numbers)?
 
:wink: Just thought I'd ask. This theory I read was several years ago, but it stuck out as being odd to me. Thanks.
