You run when you attack, you run when you retreat.

Let's do some multiplication.

Let's have a toast.

We've been running around like lunatics.

So let's make the substitution.

Good morning, my little ones. Wakey, wakey. Good morning.

So let's try a bit of an experiment.

We'll run 'em down before you can say Bob's your uncle.

He's right. We'd better run for it.

Well, then, let s do the math.

So let me do our little test here.

Now we're running a stimulus package.

So let's make a substitution in magenta.

But let's do some grouping.

So let's make that substitution.

Oh, okay. Then maybe we should take a survey and find out what other people think.

So let's make that substitution and do this.

So those are the kind of stakes that we're after.

And so at the time we were doing this research,

Uh, couldn't she have a trial? Huh? First?

We can have it altered.

Christopher McDougall Are we born to run?

In science, we do experiments systematically.

So we have to do some conversion there.

If you're cold, should we run?

Now let's do another round of row operations.

So we just do this final multiplication and we'll be done.

Kachra, this is the last ball. We must take only one run.

We could run really far on a hot day.

And to figure it out as a mixed number, we can do it in our heads now.

OK, let's do a show of hands here. How many of you use Facebook?

Let's make the substitute delta x over x is equal to 1 over n.

I think that it'll change the way that we do surgery.

And when we run experiments, we usually hope that one group will behave differently than another.

But there need not be a trade off between inequality and growth.

But, before I even do that, let's have a little bit of a review of what an exponent even is.

And we use conversations with each other to learn how to have conversations with ourselves.

We're performing a linear transformation on each of these columns.

So, let's dial this back. That's what? Fifth grade? Fourth grade?

Therefore, we should be very careful when we deliberate on those issues.

Let us celebrate, but let us also take stock of the dream yet to be fulfilled.

Next year, we hope to have a more focused debate on key issues.

We were running the same race, get more users to visit and convert.

lowest terms, or we could do it right now because it would be simpler.

So, let's dial this back. That's what? Fifth grade?
