For any integer a we have `a-0=a`

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.

Property 7 for any integer a we have a xx(-1)=-a=(-1)xx a

Associativity : For any literal a we have a+0=a=0+a Here 0 is known as the additive identity.

Property 6 (property of zero): for any integer we have a xx0=0=0xx a

Identity : For any literals a we have a xx1=a=1xx a

Property 2 (commutativity): for any two integers a and bwe have a xx b=b xx a that is multiplication of integers is commutative.

For any integer a, is a+(-1)=-a ?

Property 2 (Commutativity of addition): The addition of integers is commutative i.e.for any two integers a and b we have a+b=b+a

Property 3 (Associativity): the multiplication of integers is associativie.for any three integers abc we have a xx(b xx c)=(a xx b)xx c

If Delta is an operation such that for integers a and b we have a Deltab=axxa+bxxb-axxb , then find (-3) Delta 2.
