In this lesson, we will learn:
 What is the additive identity property of zero
 What is the multiplicative identity property of one
 How to write the general formulas/equations for the identity properties
 What are the three properties of zero?
 How the identity properties are different from the properties of zero
 How to write the general formulas/equations for properties of zero
Notes:
 The identity property is observed when the identity of the original number does NOT change after the equal sign. The answer will be the same number that you started with.
 The numbers can be any real number (whole numbers, fractions, decimals, integers, etc.)
 The word “identity” can mean who you are or what you are
 The identity property only happens for TWO cases in math:
 For addition: adding zero to any number will NOT change that number
 Ex. 8 + 0 = 8
 Ex. 0.5 + 0 = 0.5
 Ex. $\large \frac{1}{2}$ + 0 = $\large \frac{1}{2}$
 For multiplication: multiplying any number by one will NOT change that number
 Ex. 8 × 1 = 8
 Ex. 1.47 × 1 = 1.47
 Ex. $\large \frac{3}{4}$ × 1 = $\large \frac{3}{4}$
 The general formulas for the identity property (where a is $a$ variable that represent a real number) are:
 It is important to know the properties of zero – *what happens when you multiply and divide by zero so that you don't get them confused with the identity property of zero
 There are three properties of zero:
 (1) when you multiply by zero, the answer will always be zero
 (2) when zero is divided by any number, the answer will always be zero
 (3) when you attempt to divide any number by zero, the answer will always be undefined
 The general formulas for the properties of zero are:
