I gave them six GCSE questions.

But even better it looks like we can get three groups of three twos

And here, instead of dividing it into three groups like we did here.

So let me make this very clear.

Let's divide them into groups of two.

And how many groups do we have?

So I have four objects, and if I were to divide into groups of two, so I want to divide it into groups of two.

I'm going to divide it into three groups.

He's one of our group, more or less.

An example of where we've used digital stories in our work is in a training with two groups of women.

And another group of women who had survived domestic violence.

So the best way to divide it into three groups is

So you could view this is 2 times 4, and then 2 groups 4.

I've already gotten 8 and 2

So this four, which is this four, divided by the two groups, these are the two groups group one and this is group two right here.

So Archie splits the men under his care as best he can into two equal groups.

So one thing we could do, we could view this instead of 2 groups of 4 we can view 8 as 4 groups of 2.

So the answer here, and this is a new concept for you maybe, nine divided by four is going to be two groups.

And that's what division is.

There are two groups of women when it comes to screening mammography women in whom mammography works very well and has saved thousands of lives and women in whom it doesn't work well at all.

Not into three groups.

Or you could think of it the other way, if I have three groups of two.

I just picked any of them right like that.

You want to split the first degree term into two terms.

Let's say that I had 2 groups of 3.

Now what is this going to be equal to?

You could say for every group, there are two boys.

We already know that.

And I have three groups.

I have one, two, three.

I'm going to time you, how quickly you can solve this problem.

Every group has four boys and it has seven girls.

So when you divide four quarters into two groups, so this was four quarters right there.

So what Jaeggi et al did is they had four different groups of subjects trained in the working memory training procedure, some of them trained eight sessions, some of them twelve, some of them seventeen, some of them nineteen.

I have one group of two, two groups of two, three groups of two, four groups of two.

And this is how many groups of this is equal to the groups of five fruit.

And let me make that very clear.

Let's keep incrementing it.

And we have five times seven, we have five groups, five times seven, each group has seven girls.

Well, let me draw some groups of three.

And this is pretty straightforward.

Well, 4 divided by 2, I have two groups of two, so that is equal to 2.

If you divide this right hand side by 3, you have 1, 2 and 3.

Let me draw two groups of three.
