The basic properties of the real number
1. Property closed for addition of b
a, and if it is true, then b is a real number with 2
. Change group properties for the additive
if a is a real number c, b, and c (a b) = a (b c)
3. The properties are unique for the additive real numbers are 0, 0
a = a = a 0 for all a. It is called additive identity 0
4. The property has an additive for the server
.For a real number for each have a real number a, a-a-a = 0 = (a-a) call-a river that's positive for an a
5. commutative properties for the additive of a and b
, if true, then a b = a
b
