Well, what's going to happen?

This will cancel with this, and so you're just left with the first 3 of 7 factorial.

When we did 7 things into 3 spots we went 7 times 6 times we literally put in the top three of you could almost say from the factorial.

We have a well actually I forgot to do this should be 9 factorial.

The cop's chasing me.

Which is, let's see, 9 times 8 is 72.

Seven? Seven?

Well, in our example, k was the number of spots, and there were 3 spots.

6 7 minus 6 7 is 0.

Fourth floor. Fourth floor. Come on.

So 7 27's.

Which just means that the 7 keeps on repeating.

Let's see.

Actually, let's just do what we did up here so you don't have to remember that difference of squares pattern and all that.)

Seven decks.

Seven... Seven... Sevenzeroniner.

They wore masks. Just make sure nobody gets out.

Cover the left over there, cover the exits!

Plus one is eight.

And if we simplify, what do we get?

If this was just 3 was so 7 times 6 times 5 times 4 times 3 times 2 times 1.

That's 5 7.

I could have a matrix that looks like this, where its 3, 5, 0, 0, 1, 7

They want us to multiply something.

You subtract.

There's no where to put the five, so we put it down here.

7

7

Seven, and yours?

I have a class at 7 30.

I want combat seating.

7 30.

Seven

You take downstairs, I'll go up.

7 times 9 is 63.

It goes into 12 one time.

7 times 7 is 49, so it goes into it seven times.

This is 0.

This evaluates to 9. 7 is exactly 7 to the left of 0.

Seventy seven times seventy seven.

Put a four there.

So you have minus 11 over here. So this is the 7

We write the six down here, put the five up there.

Well, that's fifty four.

It does go into 51.
