It literally could mean, so 2 5 times 7,

So that's four 2 5.

That's easy, that's 0.

And so this would be your change in x.

5.2.

Yes, that's minus 4, 6 minus 10, right?

And that's what?

We have 2 times 1 plus 5 times 0, that's 2.

And what is that equal to?

1 2 3.

You can tell, this is often better done by a computer.

So, 1, 2.

I could put e there.

Tango... five... niner... two... November.

The first term has one 5.

Let's say let me pick some random numbers

And let me multiply that by B. 3 minus 4.

So we go to the ones place.

Negative 2 times 7 is negative 14.

25...

So this is what?

So this row times each of these columns, right?

Now lets do the same thing with n equals 5.

1, 2, 3... 1, 2, 3, 4, 5,

So let's try this first one negative 2.

Down the road.

That's five 2 5.

We just take this 3, and we substitute it in for x.

All you're going to be left with is a v.

Let's see that's one two.

So that's one, two, three, four.

We have it right over here.

So we're going to go to the right 5

It equals two.

One, two, three ,four, five, so that is 1 3 right there.

But the other five cards are going to be different.

And where did I get seventeen from?

Let's do the row before you, starting with you one, two, three, four, five.

So let's divide each into 5.

1, 2, 3, 4, 5.

And I could even divide this into 5 if I want.

Five, four, three, two, one.

We are running at 2. 5 Volts.

Five. Four. Three.
