And here is Gauss' trick, for observation, which is that the result of the third recursive call minus each of the first two what happens.

This is really just an exercise in algebra.

We have a positive 2 and a minus 2.

8 is 2 to the third.

Let me erase some of this.

That crosses out. a squared minus a squared crosses out. a to the third, it'll all cross out.

The left hand side, we're just left with the 3x.

Let's see, this z plus 2 cancels out with this z plus 2.

that's equal to x minus f squared plus y squared.

Negative 1 3 times 6z is going to be minus 2z.

Then times 5 times 4 times 3 times 2 times 1.

But the best thing, I'm guessing, is to just factor these out and all sorts of things will start canceling out with each other.

Well, we take the exponent, multiply it by the expression.

We know that f of 2 is 8. 2 3 is 8

2x minus 5 is equal negative 11 let's add 5 to both sides of this equiation.

If you wanted to solve it algebraically you could add 11x to both sides and both of these terms will cancel out with each other and all you would be left with is a 4 is equal to a negative 11, which is not possible for any x that you pick.

Subtract 49 from both sides.

So that's 6.

Well, a to the first, minus a to the first.

Well, that just equals 1 3 again.

And now let's add for the new variance, a 1000 to each individual salary and a 1000 to the mean.

But this is equal to a squared minus b squared, because the middle terms cancel out.

I'll leave you guys with this

The Klingons have threatened to retaliate with everything they've got.

And already it looks like there's some cancellation that we can do.

If I have a negative times a negative, the negatives are going to cancel out.

Now we can add 13 to both sides of this equation so that we get rid of it on the left hand side.

And their batting average is very simple.

The one who vanquished the tyranny of the user those many cycles before!

So you've effectively negated 60 years of aeronautic research.

Now, Alice ads her private colour to Bob's mixture.

Many of us are hostile to the consumption tax.

So what happens when little artists get locked in, banished or even killed?

He always behaved badly to me.

Many consumers rose up against the consumption tax.

You can add x squared to both sides to get rid of this and this.

And they don't always work together.

That makes it three balls and one strike on Wills, hitting right handed against Warren Spahn.

Multiplying this out misses exactly 1 term, pXi, which is number 3.

And that's why I put the 1 2 there.

The power lines are getting overloaded.

That is the ethos found, too, in all the religions.

At last he unfolded his plans for their future.

So that's going to be equal to 6y squared minus x squared plus 3.
