A negative times a positive is a negative, or a positive times a negative is negative.

A negative divided by a negative, just like a negative times a negative, you're gonna get a positive answer.

Negative times a negative is a positive.

Negative times a negative is a positive.

A negative times a negative equals a positive.

A negative times a positive is a negative.

A positive times a negative is a negative.

If it's less than negative a, maybe it's negative a minus another 1, or negative 5 plus negative a.

Just a negative times a negative is a positive.

The negative times a negative is a positive, but then we're multiplying that times another negative, so we get a negative.

And then you have a negative times a negative.

We have a negative 4 times a negative 10.

Well, we all learn from multiplying negative numbers that a negative times a negative is a positive.

It then becomes a negative 9 plus 3, it becomes negative 3, and negative 3 will also become a negative 3.

And a negative times a negative is plus 5b squared.

Well, all of a sudden, negative 2 is more negative than negative 1.

And so negative twenty one ( 21) divided by negative one ( 1), negative divided by a negative is going to be a positive.

Let's go negative, negative 1, negative 2, negative 3, negative 4, negative 5, negative 6.

So negative 4 times 3 is a negative 12.

Not that negative, it's like a fractional negative slope.

Negative 10, negative 9, negative 8, negative 7.

Now I can do it with the negative 'b'. Negative 'b' times 'a' is negative 'ab' (or negative 'ba', same thing) and negative 'b' times 'b' is negative 'b 2'.

We have a negative 11x here, we have a negative 11x there.

Or they're both negative, so that when you divide a negative by a negative you still get something positive.

And then you put a negative there, so it's negative 4 the point here is negative 2, and then negative 4.

If you had a negative an a plus, or negative and a plus sometimes cancel out, or a negative and a negative, that's the same thing as just having a plus on top.

So this is a negative inverse of negative 2 5.

And then negative 15, if you factor out a negative 5, you divide negative 15 by negative 5, you're just going to have a positive 3.

He can't sell a negative 1 ticket or negative 2, so it's anything that's non negative.

Let's see, if we go to negative 1, negative 1 this will become a negative 1.

Negative 3 squared is positive 9, you have a negative out front, it becomes negative 9 plus 6, which is negative 3.

You can view this as a negative 1 or, this negative divided by a negative, they're going to cancel out.

Negative 5. Negative 6. Negative 7.

Then we would have a negative 1 right there, maybe a negative 2.

Because 2 times a is going to be negative 4. a is negative 2, and if a is negative 2, what is a squared?

So we can just distribute the negative sign and negative one times six is negative six let me do these in magenta so this is negative six, and then negative one times negative eighteen i, well that's just going to be positive, positive eighteen i negative times a negative is a positive.

So the slope was negative, less negative, 0, a little positive.

It becomes a negative 2 So it becomes 2, negative 1.

And then, negative b times a positive b, negative b squared.

But if you multiply a negative times a negative, you're going to get a positive.

That's a negative 21.

That's a negative number.

It's a negative number.

It's a negative slope.

So this will be a negative over positive, and will get a negative number
