We have x's on both sides of the equation.

Those are the types of things that you will look at and feel.

The minus 1 times negative 2.

Absolute value of negative 3 is positive 3.

This would be positive.

If I did it to the left hand side I have to do it to the right hand side.

And because I have a negative divided by a negative, the negatives cancel out, so my answer will still be positive six (6)!

Let's say it's a helium atom.

Well, it equals, this is nothing.

And then we have all of that over negative 20.

So be careful when you take that square root.

60 plus 10 is 70.

So then this becomes a plus.

Of course, we have our dt, and you have a minus minus.

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

So these two would be the same thing as subtracting 550.

It'd be 2 times 0, which is 0.

If x was 1, y would be 2 times 1, which is 2.

I had 63 seats, I'm now adding 18 seats.

A positive times a negative is a negative.

You could also say that as when the signs are different and you multiply the two numbers, you get a negative number.

That is equal to 92 degrees.

For K 7, this minus data point will have 4 pluses, 3 minuses over here, and then everything in the vicinity becomes positive, so it must be 4 plus and it will be mis classified.

Well, 2 times 7 is 14, and we have the same sign here, so it's a positive 14 normally you wouldn't have to write the positive but that makes it a little bit more explicit.

It must mean that the country had something so advantageous to itself in terms of economic growth to overcome the negative effects of the Cultural Revolution.

I think everyone would have a different interpretation of it.

But here we have a negative times a positive 2, and it turns out that when you multiply a negative times a positive you get a negative.

So we have 7x, negative 2 plus 2 is just 0.

This guy has in his 5 neighborhood these 3 pluses over here, plus a minus, plus a plus.

So that first value, on this number line, so all of these are absolute values.

So that's another rule.

Boy, I'm glad that was not too difficult to find.

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

So if a is 8 we could rewrite that expression I'll switch colors arbitrarily as x squared plus 16x plus a squared.

So if we factor out a negative sign, then this will become negative.

Plus his mattress is gone.

So, in this example, a is minus 10. b is minus 9, and c is 1.

Because f of x equals 0 when you're intersecting the x axis.

It also conveniently tells you what time it is back home.

Negative times a negative give me a positive.

4 times 201, that's the same thing as 4 times 200, which is 800, plus 4 times 0 tens, which is 0 tens, plus 4 times 1, whis is 4.

And so we know that this left hand side of this equation is x minus a or x plus a, but a is a negative number.

So a is equal to 20 plus 30, which would mean a is equal to 50.

Now negative sixteen ( 16) divided by positive four (4) now be very careful here.

We're going to introduce 2 other list operations. The next one is plus.
