ZERO

why zero is called as identity for the additional of rational numbers? and

also why it is also a additive identity of whole numbers and integers?

one thing i know about zero is , if it is used as an operation to any number , the result is the same number ex: in add, subtraction

ex: a+0 = 0+a = a

these points u have read in cbse 8th class ,

can anyone clear this point pls

thank you

a +0 = 0+a = a is exactly why 0 is additive identify for whole numbers, integers and rational numbers.

Similarly, 1 is the multiplicative identiy. a * 1 = 1 * a = a.
