So let's add this up.

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

It is whole numbers plus negative of natural numbers

So let's write that first rule down.

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

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 you subtract 8 from both sides.

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.

That's a minus x.

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

okay. pretty good, right?

Anode.

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

So different signs mean negative.

Remember, different signs will get you a negative result.

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

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

Negative 1 times this is positive.

Negative 1 times this is negative.

You can view this as a negative 1 times all of this.

I'm doing it in pink, because it's the inverse.

That's minus 1 squared.

So let's just make that times plus 2 and put the plus out there.

So what's 1 2 of this coefficient?

So it's two minus negative three.

Well, f of 0 is equal to we could do it right here f of 0 is 0 plus 7 times 0 minus 4 is just 7 times minus 4, which is minus 28.

Negative 1 3 times 6z is going to be minus 2z.

We have negative two and one fourth. So let's go to negative two.

So that's another rule.

But I can rewrite minus 2, right?

And then you just do the distributive property.

And we have a negative times a negative. They cancel out.

sir, just ask yourself, what would jesus do?

Positive, negative.

The same is true for K 9.

So let's do that.

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