You write the two columns again, you say, ok, this product plus this product plus this product, minus this product minus this product minus that product.

Output

And now the rule of Sarrus I just take this product plus this product plus this product and then I subtract out this product times this product times this product.

And you're raising it to the third power, so that equals twenty seven.

KXSLDbg Output

(b) Output

World output 1.6 0.3 0.8 1.1 2½ 3

So what is this?

It's equal to 26.

That's a positive.

So I get nothing!

It is 91.

That's three.

This is sixteen.

This will raise actual output to the level of potential output, thereby closing the output gap.

Add the following output

Per cent of 1990 GDP

Output growth a

percentage of GNP

GDP 1989

Well that's just a positive.

It's seventeen.

Goes into it one time.

And what's that?

You get 68.

So that's 0.

It's a two.

It's going to be sixty three.

And what's this going to be?

And then that equals minus sixty four.

So what is this whole number going to be?

And what does that give us?

So let's see what it is.

Let's see what it is.

Well it is just going to be seven.

And then this becomes a 5.

And so what is that?

7 times 1 is 7, so it's 896.

So that is equal to 2.

I'm going to get b.

So it's 31.5.

It turns into that.

What does this become?

That's just minus 1.

So what is that going to be?
