    The identity property of addition states that the sum of 0 and any other number is that number. This is because adding nothing to any number just leaves the same number, since 0 has no magnitude. It can be written as follows, where a is a variable that represents any number. a + 0 = 0 + a = a. Any value can be substituted for a.
