The whole country went mad.

I'll try to color code it negative three and then another negative three or you could say negative three minus three or, and this is the interesting thing, instead of over here there's a two times positive three you added two, three times.

It's not all perfect and easier and improved.

So we get x plus 8 is equal to plus or minus 11.

It is true that television also has some disadvantages.

So let's add this up.

So this is these two terms that I'm adding together.

This is really a great way to program. It's very declarative. You just say what you want, and the system makes it for you.

It is whole numbers plus negative of natural numbers

That's minus 1 squared.

That's a minus x.

So it's two minus negative three.

We could be equal to it or greater than, but we have to be less than minus 4.

So what's 1 2 of this coefficient?

So let's write that first rule down.

And the other root would be 9 minus 11 over negative 20.

The same is true for K 9.

You could view this as negative two repeatedly added three times.

This is going to be equal to some stuff over 300.

And that works out, right?

So with cities, you also have congestion and pollution and disease and all these negative things.

We can be greater than or equal to minus 11.

And I wrote it that way so I have a common denominator.

We know that f of 2 is 8. 2 3 is 8

And all of that over 2 times a.

I'll let you think about why you only have to write it once.

So you subtract 8 from both sides.

You can have an x, so x has to be we can rewrite this greater than or equal to minus 11.

So let's review.

Negative times a negative is a positive.

A negative times a positive is a negative.

So it's going to be five times ten. It's going to be fifty.

Plus negative two. which would be equal to well, negative two plus negative two is negative four, plus another negative two is negative six.

So if I were to say negative five times negative ten well, once again, negative times a negative.

And then finally what if it I had let me think of some good numbers minus 6 times minus 11.

So if I were to multiply I'll just switch colors for fun here

okay. pretty good, right?

Anode.

We have negative one point two. So negative one is right over here.

Let's do two times negative three, I want to make the negative into a different color.

You've learned that if I had, say, x squared minus x, minus 6, equals 0.

So different signs mean negative.

Remember, different signs will get you a negative result.

If I just said thirty (30) divided by five (5), I'd get a positive six (6).

Negative 1 times this is positive.
