Chapter One :

Combining Digits,
A number line is the key,

Subtracting Integers - Free Verse

Take away from that,
That is what you call subtract.
and maybe even better,
do the rest and you are done.

Partitive Division - Tanka

Use equal parts here,
Imagine dealing out cards.
Give some to each group.
Make sure it's equal,

Quotative Division - Free Verse

Peek-A-Boo, I see you.
Find me in, a number bin.
How much of me, can you see.
Circle me how many times,
Don't worry it's not a crime.
The number of me,

Ron's Rule - Free Verse

Ron's rule isn't hard,
Just use when multiplying.
Negative numbers,
Odd is Negative,
And just vice versa.

Thanks for reading and here's a little extra since I put this off to the last minute.
Hope you enjoy.

Chapter 2 :

Combining Like Terms and the Distributive Property.

Pog: Hey
Pog: I'm kind of low on money as you can see from my clothes, so I was wondering if you could make me a bank account.
Adalrico: Surely I could do something. Although, in order to obtain an account, you must go through a series of questions. It's a new policy that the manager has created.
Pog: Yeah whatever, as long as I get my account. I haven't eaten in days you know.
Adalrico: Well the first question isn't that hard, and if you graduated in school, you should answer this easily.
Pog: Alright then.
Adalrico: The first question is "n+ 3 -5n +12"
Pog: Algebra huh? That rhymed, im a poet and I didn't know it.
Pog: Well, I remember something about this in school. Maybe if I bring the N and -5n together, so then if i have negative 5 n's, and I add the other n, that would equal to negative 6 n's (-6n). Is that right so far?
Pog: Fine then. So now, I'm left with -6n +3 +12. This part is easy, I just add the 3 and 12 to get 15. So my complete answer is now, -6n +15. Is that right?
Adalrico: I'm sorry sir, but that is incorrect.
Pog: What!? Show me then if your so smart.
Adalrico: Well, the last part you did was right, the part where you got positive 15. The part where you got wrong was when you were adding the variable.
Pog: Very what?
Adalrico: The variable, the unknown number. The n.
Pog: Oh okay, so how do I do it then?
Adalrico: Well sir, as you can see, there is no negative sign in front of the n. Although, there is a negative sign in front of the 5n. So, it's a simple addition question. Add 1 positive n to 5 negative n's. What would that equal?
Pog: Uh, it would equal a number.
Adalrico: Wow, it's very simple. That equation would equal to negative 4 n's (-4n).
Pog: So the right answer would be -4n +15?
Pog: I knew it! Well, kind of.
Adalrico: Well Pog, you could still get your bank account, but you would have to answer at least one question right. Would you like another question?
Pog: Bring it on then, I'm prepared for anything you give me.
Pog: Umm, hold on, let me try and remember what to do if there is brackets. I got it! When a bracket is touching a number, you multiply the two. So 4 multiplied by 3n. I think that would equal to 12n! Now that the brackets are gone, I'm left with 2+12n+8. Since I can't add the 2 to the 12n, I add it to the positive 8. So then, that would equal positive 10!
Adalrico: Once again, you are wrong.
Pog: Are you for real?
Adalrico: Sadly, yes. You messed up when you saw the brackets. It's true that you multiply when a number is touching a bracket, but in this case, we will use the Distributive Property.
Pog: Okay then, but how does it work?
Adalrico: When a number touches a bracket, the number outside of the bracket multiplies the numbers inside the brackets. So since the number touching the bracket is +4, and one of the numbers inside of the brackets is 3n, we multiply those two.
Pog: So it would be positive 4 multiplied by 3n right?
Pog: Well, if I have 4 groups of 3n's, then I would end up with 12n's! Right?
Adalrico: Yes, now since there is one more number inside of the brackets, you multiply the four with that number inside.
Pog: So, since a positive 8 is still in the brackets, you multiply that with the positive 4. Am I correct?
Adalrico: Of course. That would equal what Pog?
Pog: Uhmm, 4 groups of positive 8 would equal, 32!
Adalrico: Correct once again. Now tell me the all the integers you have so far.
Pog: 2 +12n +32. Just like the first question, I add the same type of numbers. Since the 12n doesn't fit in with anything else, I add the other two integers.
Pog: Finally, an easy question. 2+32 would simply equal 34.
Adalrico: Do you know what to do next?
Pog: Of course, you put the two integers together and create an expression.
Adalrico: And that expression would be?
Pog: It would be positive 12n +34.
Pog: Yeah, now may I have my bank account, I'm getting pretty hungry.

Anyways, I made two videos because my script couldn't fit on one movie.
