And let me do it one more time.

Given the data set, instead of just splitting it into a train and test set, what we are going to do is instead split it into three pieces.

Well, I have x total fruit.

So they write, x squared plus 8x plus 16, over x plus 3, divided by 2x plus 8, over x squared minus 9.

5 over 35 I'm leaving some space so we can divide well, these are both divisible by 5, so let's divide the numerator and the denominator by 5.

If we do the same thing to numerator and denominator we're not going to be changing the value of fraction.

So let's divide by 3.

Divide these just like that, and then divide these just like that.

And these are both divisible by 2, so if you divide the numerator by 2, you get 3.

No, we start with a loaf of bread and we cut it into smaller pieces called slices, so each slice of bread is a partitioned unit.

I have something divisible by 2 into the denominator, so let me divide the numerator by 2, and this becomes a 1.

And you can simplify this the numerator and the denominator are both divisible by 4

And then it would have been more obvious that you can divide the numerator and the denominator by 2 once you can do it again and then you'd just be left with one over two times 5 times 5.

Both the numerator and the denominator are divisible by 3.

He just waltzes in and cuts in line?

It's vasebreaking time. It's what?

let's keep track of the areas of the pieces.

You could have said, OK, let's see.

There are 38,000 suicides each year in the United States.

It's going to recurse on either the left or the right.

Nothing too complicated there.

Splitting 5.

A lot of systems both shard and replicate your machines if you really want to get fancy.

And the only times that g of x is equal to 0 is when x is equal to negative 2 or x is equal to negative 8.

I prefer payment in full to payment in part.

And then we're left with 2 3 and 1.

Split future recurrences

Both our numerator and our denominator have numbers that are divisible by 4, so let's divide both the numerator and the denominator by 4.

Let's go Dutch today.

Let's split the bill today.

Divide the numerator by 3, you get 1.

So it's 6 36 which we can simplify since it is just a fraction.

So, that was model selection and how you can take your data and split it into a train validation and test set, and use your cross validation data to select model and evaluate it on the test set.

So divide the numerator by 3, and let's divide the denominator by 3.

So 27 divided by negative 12, well, they're both divisible by 3.
