7:55 PM: John Beck(Ins): In fact, we just clicked on Tools, then Calculator.
7:55 PM: Loredana Lungana: I'm there
7:56 PM: John Beck(Ins): Since we'll be taking our tests online this semester, we need to get familiar with the calculator.
7:56 PM: Hollynn VanCourt: Is it ok if we use our own calculators?
7:56 PM: John Beck(Ins): If you click on 8, then n!, then = we'll get the answer.
7:56 PM: John Beck(Ins): Did you get 40,320?
7:57 PM: Mary Stilling: Yes
7:57 PM: Susie Brooks: yes
7:57 PM: Hollynn VanCourt: yes

7:57 PM: Edith Panzarella: yup
7:57 PM: Amy Matheny: yup
7:57 PM: John Beck(Ins): I will embed a calculator that is appropriate for the test you are taking.
7:58 PM: John Beck(Ins): But, you can always use your own calculator.
7:58 PM: John Beck(Ins): Let's click on "off" please.
7:58 PM: John Beck(Ins): Go to page 11, please.
7:58 PM: John Beck(Ins): 6! = 720.
7:58 PM: John Beck(Ins): Go to page 12, please.
7:59 PM: John Beck(Ins): This Fundamental Counting Property will be with us for about 6 more weeks!
7:59 PM: John Beck(Ins): Go to page 13, please.
7:59 PM: John Beck(Ins): Go to page 14, please.
8:00 PM: John Beck(Ins): By definition, we assign 0! = 1
8:00 PM: John Beck(Ins): It's our game!
8:00 PM: John Beck(Ins): Later today we'll see why we had to assign 0! = 1.
8:00 PM: John Beck(Ins): Go to page 15, please.
8:00 PM: John Beck(Ins): You might see some of these on the online test!
8:00 PM: John Beck(Ins): Go to page 16, please.
8:01 PM: John Beck(Ins): Pretty simple stuff.
8:01 PM: John Beck(Ins): Go to page 17, please.
8:01 PM: John Beck(Ins): We could have used our calculator.
8:01 PM: John Beck(Ins): Go to page 18, pleas.

8:01 PM: Christina Eisenhuth: ok
8:01 PM: John Beck(Ins): Go to page 19, please.
8:02 PM: John Beck(Ins): In the numerator (top) I stopped at 5! since I knew I had a 5! in the denominator (bottom).
8:02 PM: John Beck(Ins): Go to page 20, please.
8:03 PM: John Beck(Ins): I've cancelled 5! in the numerator with 5! in the denominator.
8:03 PM: John Beck(Ins): Go to page 21, please.
8:03 PM: John Beck(Ins): Whew! We got the same answer.
8:03 PM: John Beck(Ins): When we work with particularly large numbers, Class, you're going to have to cancel before you can press the = button.
8:04 PM: John Beck(Ins): Go to page 22, please.
8:04 PM: John Beck(Ins): Once again, I stopped at 8! in the top since I had 8! in the bottom.
8:04 PM: John Beck(Ins): Go to page 23, please.
8:04 PM: John Beck(Ins): Cancel common factors!
8:04 PM: John Beck(Ins): Go to page 24, please.

8:05 PM: John Beck(Ins): Notice that the word PERMUTATION is in bold?
8:05 PM: John Beck(Ins): Hmmm. Must be important.
8:05 PM: John Beck(Ins): Go to page 26, please.
8:06 PM: John Beck(Ins): By the way, being the president isn't the same as being the secretary, etc.
8:06 PM: John Beck(Ins): Go to page 27, please.
8:07 PM: John Beck(Ins): Repetition isn't allowed -- nobody can perform twice and nobody can be both president and secretary.
8:07 PM: John Beck(Ins): In general, we have permutations when repetition isn't allowed.
8:08 PM: John Beck(Ins): Order is important -- If you are playing in this recital, you might tell a friend that you are playing 3rd or you are playing first -- order is important.
8:08 PM: John Beck(Ins): Go to page 28, please.
8:08 PM: John Beck(Ins): Math types love formulas!
8:08 PM: Edith Panzarella: ugh!
8:09 PM: John Beck(Ins): Here's our first formula. It is for the Permutations of "n things used r-at-a-time."
8:09 PM: John Beck(Ins): I supply the formulas. You need to know when and how to apply them!
8:09 PM: John Beck(Ins): Go to page 29, please.
8:10 PM: John Beck(Ins): Notice I have the first 6 letters of the alphabet.
8:10 PM: John Beck(Ins): Go to page 30, plese.
8:10 PM: John Beck(Ins): Go to page 31, please.
8:10 PM: John Beck(Ins): Looks pretty simple to me.
8:10 PM: John Beck(Ins): Go to page 32, please.
8:11 PM: John Beck(Ins): Hmmm. We've seen stuff like this tonight.
8:11 PM: John Beck(Ins): Go to page 33, please.
8:11 PM: John Beck(Ins): I stopped at 4! in the numerator since I had 4! in the denominator.
8:11 PM: John Beck(Ins): Go to page 34, please.
8:11 PM: John Beck(Ins): Cancel common factors.
8:11 PM: John Beck(Ins): Go to page 35, please.
8:12 PM: John Beck(Ins): Now we need to look at these 30 permutations.
8:12 PM: John Beck(Ins): Go to page 36, please.
8:12 PM: John Beck(Ins): Here are 5 of them. They all begin with a
8:12 PM: John Beck(Ins): Go to page 37, please.
8:12 PM: John Beck(Ins): There 5 all begin with b
8:13 PM: John Beck(Ins): Notice that we have ba here which is difffent than ab from the first column.
8:13 PM: John Beck(Ins): Okay?
8:13 PM: Hollynn VanCourt: yes
8:13 PM: Mary Stilling: Yes
8:13 PM: Loredana Lungana: yes
8:13 PM: Edith Panzarella: yes
8:13 PM: Stephen Scott: yep
8:13 PM: John Beck(Ins): Also notice that we don't have aa nor do we have bb -- repetition isn't allowed!
8:13 PM: Susie Brooks: yes
8:13 PM: Anissa Watkins: yup
8:13 PM: John Beck(Ins): Go to page 38, please
8:14 PM: John Beck(Ins): ca and ac aren't the same
8:14 PM: John Beck(Ins): Go to page 39, please.
8:14 PM: John Beck(Ins): Here are our 30 permutations.
8:14 PM: John Beck(Ins): Now we need some examples.
8:14 PM: John Beck(Ins): Go to page 40, please.
8:15 PM: John Beck(Ins): Those of you who go to the races, this is an exacta.
8:15 PM: John Beck(Ins): There are 30 exactas in a 6-horse field.
8:15 PM: John Beck(Ins): Go to page 41, pleas.
8:16 PM: John Beck(Ins): Go to page 42, please.
8:16 PM: John Beck(Ins): Sounds like a permutation to me!
8:16 PM: John Beck(Ins): Go to page 43, please.
8:16 PM: John Beck(Ins): Go to page 44, please.
8:17 PM: John Beck(Ins): Hmmm. We have 0! in the denominator.
8:17 PM: John Beck(Ins): Go to page 45, please.
8:17 PM: John Beck(Ins): Whew! We defined 0! as 1.
8:17 PM: John Beck(Ins): Go to page 46, please.
8:18 PM: John Beck(Ins): So the guy is getting ready to print the program would have to print 120 different programs and then choose the one that matched the teachers choice of players.
8:18 PM: John Beck(Ins): Go to page 47, please.
8:19 PM: John Beck(Ins): Go to page 48, please.
8:19 PM: John Beck(Ins): Hmmm. A new vocabulary term.
8:19 PM: John Beck(Ins): A combination must be different than a permutation.
8:19 PM: John Beck(Ins): Go to page 49, please.
8:21 PM: John Beck(Ins): When I buy my numbers I might have: 1, 7, 15, 23, 25, 30 but when they actually draw the numbers they might have: 7, 1, 25, 23, 30, 15
8:21 PM: John Beck(Ins): Did I win?
8:21 PM: Mary Stilling: No
8:21 PM: Amy Matheny: yes
8:21 PM: John Beck(Ins): THAT"S RIGHT, ORDER ISN"T IMPORTANT
8:22 PM: John Beck(Ins): hitting the ' instead of the " is important.
8:22 PM: John Beck(Ins): Do you agree that I win?
8:22 PM: Hollynn VanCourt: yes
8:22 PM: Mary Stilling: yes
8:22 PM: Susie Brooks: yes
8:22 PM: Loredana Lungana: yes
8:22 PM: John Beck(Ins): ORDER ISN'T IMPORTANT.
8:23 PM: John Beck(Ins): Go to page 50, please.
8:23 PM: John Beck(Ins): Repetition isn't allowed.
8:23 PM: John Beck(Ins): But order isn't important.

8:25 PM: Loredana Lungana: :)
8:25 PM: John Beck(Ins): Stop at 5! because we're going to cancel common factors.
8:25 PM: John Beck(Ins): Go to page 56, please.
8:25 PM: John Beck(Ins): Go to page 57, please.
8:25 PM: John Beck(Ins): We need some examples.
8:25 PM: John Beck(Ins): Go to page 58, please.
