- Fundimental Principal of counting
- Factorial Notation
- Permutations
- Permutations of Non-Distingushable Objects
- Circular Permutaions
- Combination

- n! = n · (n-1) · (n-2) ...etc
- r = generally means the amount of objects to be arranged
- P = "pick"
- c = "choose"
- i = term? not sure about this one

The ideas were simple but i have most difficulty on finding what formula to use for a problem. Like to choose the "pick" or "choose" formula.

Also, circular permutations and middle terms are difficult for me to understand.

OH I loved how Mr.K showed us how math applies to what we believe is beautiful. I wish we could have went more indepth with that. Math is EVERYWHERE.

Note to self:

- It is easier to just draw a diagram!
- Permutations are when order matters.
- Combinations are when order does NOT matter.
- Mr.K has Math Powers.
- when solving certain problems with permutations with 0, o's are special!
- (n "over" r) is NOT (n/r)
- im tired.
- Don't take on too many things at the same time :|
