Bob: Hey, i'm bob.
Borock Obama: Hey, i'm borock Obama.
Bob: May i ask you a question Borock Obama.
Borock Obama: Sure, I guess, but what is the question about ?
Borock Obama: okay.
Bob: What is n+3-5n+12.
Borock Obama: negative 6n+15 .
Bob: Wrong, the answer is -4n+15
Borock Obama: How so ?
Bob: The first "n" means positive 1, and the second "n" is negative 5n. The positive and the negative integers cancel each other out leaving negative 4n . Canceling out the positive integer and the negative integer was your mistake.
Borock Obama: I see. Give me another question please, i'll get it correct.
Bob: okay, 2 + 4 bracket 3n+8 bracket .
Borock Obama: 12n + 10, i'm sure of it.
Bob: That's wrong again, the real answear is 6n + 32.
Borock Obama: How , i was so sure it was 12n + 10 .
Bob: You didn't use Distributive Property.
Borock Obama: Seriously !
