9. IDENTITY PROPERTY Multiplicative Additive This means that you can multiply 1 to any number...  and it keeps its identity!  The number stays the same! Let's look at the number 8.  Anyway we try to multiply 1 to it, the 8 just keeps coming back as the answer. This means that you can add 0 to any number...  and it keeps its identity!  The number stays the same! Let's look at the number 5.  Anyway we try to add 0 to it, the 5 just keeps coming back as the answer.
