You could do even something more impressive the sum from 1 to 1,000.

We're going to add up all the columns in up and down direction, right?

Well, that's just 2S.

Final count...

(Let me write this down, I covered up my old total).

And this is the easy part.

I'll use an A colon.

So what's the total amount of time that he would have traveled on that day?

It's one way here, and two from above.

And then for each of those nodes what we do is we sum up for all the pairs of nodes that are neighbors of the node v.

What is the total amount?

So if you have one circle like that and then you have another overlapping circle like that.

You end up with 4, 14, 3 and 1.

We have a positive 2 and a minus 2.

Another way to think about it is

The question now is how many total constraints do we have if we count each of these constraints as exactly one constraint.

What is my assets minus my liability?

It's small and large. This is an ashtray, a water glass.

And then you could come from above as well.

So six again.

30 ways from behind it.

That's very straight forward. I call it the h2.

I'm going to sum, sum of

Here's one shell that goes around.

And then we move 200 more.

Well I can go from here, here, here, or here.

And if we want the total surface area she has to paint, it's going to be the sum of the two cubes.

But you can do more interesting things.

What is the value of y?

Well, the total is always the sum of its parts.

If I'm the sum, I'm 30. If I'm the difference, I'm 10.

We kind of moved a little bit away from the goal according to the heuristic.

And then one way from above.

Well, three from behind and three from above.

That's the height of that rectangle.

Total, 60 gallons.

For the weighted average we get 2 times 10 plus 8 times 13.

So the volume, 405 let me do it this way.
