October sixth.

And then we subtract.

It's a bad habit.

Ten. Nine. Eight.

That's obtained by 10 x 12 10 x 8 is 200.

So let's just keep going.

So we're ready to subtract.

So 0, 1, 2, 3, 4, 5, 6 I'm doing them small so I know I can get to 15.

And if you subtract 11 from that, you go back 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.

Thrun And the answer is just add those up. 8 10 18 4 6 10

But we want a positive 4, so let's do negative 6 and 10.

That's what's?

Let me switch colors.

So we have all of our factors here

And then you can verify. The area is 6 times 10 times 1 2, which is 30.

The second velocity is 20 multiplied by 0.1 gives us a 2.

We only multiplied all the way to 7. These are the 4 heads that we placed.

If we go vertically, we have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

It's going to be 5 times 2 plus 6 times 4.

I think I'm running out of space.

Look at the x's 5, 6, 7, 8, 9, and 10.

Then you get a negative 4, if you added these two.

Jump in ten... nine, eight... seven, six, five... four, three... two, one.

You could borrow from here. That will become a 6

And if this width is 6, then this width must be 6 as well. And now we can figure out the perimeter.

'Poisonwood', 'Bible' , and the function we're trying to maximize is len the string length function.

Let me draw some.

1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

There's 1, 2, 3...actually I'll use another color.

Now all we have to do is count the intersections.

2 times 3 plus 5 times minus 2.

Ten, nine, eight, seven... six, five, four, three... two, one...

So this blue expression over here will go from 10 x 9 x 8 and so on all the way to 1 over now n k, 10 4 is 6.

We put the six in the ones place.

So this is times 10 to the sixth.

Negative 7 minus 3 is negative 10.

For example

So, here's another time lapse shot of Columbia.

You write a six in the ones place.

So one whole is 10 tenths, we're in the tenths place.

1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

So 10 divided by 2 is 5, so this will result in 6, plus 10 divided by 2, is 5.

I could take f of 3, which is 2 times 3 plus 4, which is equal to 10.

If I asked you what twelve divided by four is so let me do twelve.

But let's prove it to ourselves.
