Existence OF limit

Existence of additive identity

Property 4 (Existence of addition identity): There is integer 0such that for any integer am we have a+0=a=0+a The integer 0 is called the additive identity.

EXISTENCE OF RIGHT IDENTITY - The rational number 0 is the right identity.That is for any rational number (a)/(b) we have (a)/(b)-0=(a)/(b)

Property 3 For any integer a we have a-0=a i.e.0 is the right identity for subtraction.
