The identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity."
this is the identity property of addition. 5 + 0 = 5 the 5 gets his idenity back the identity property of multiplication is 1 becuase 1 x 5 = 5
The Identity Property
the additive inverse property states that a number plus it's opposite equals zero. in other words, x + (-x) = 0 example: 5 + (-5) = 0
Identity
The zero property because it has a zero.

Identity
The zero property because it has a zero.
5+x=x+5 is an example of the commutative property of addition.
(5+5) + (5-5) + (5 + 5 - 5) + (5 x 0) = 10 + 0 + 5 + 0 = 15
Due to a special property of zero, x+0 is the same as x.
5 + 5 + 5 - 5 + 5 + 5 - 5 + (5 x 0) = 15
x+4x+5 = 0 5x + 5 = 0 5x = -5 x = -1
x = -1/2 or -5 2x2 + 11x + 5 = 0 ⇒ (2x + 1)(x + 5) = 0 ⇒ (2x + 1) = 0 → x = -1/2 or (x + 5) = 0 → x = -5
The existence of an additive identity, denoted by 0, which has the property that x + 0 = 0 + x = x for all x belonging to a set of numbers.
