You decode what you want to fold up into, into a sequence of angles so negative 120, negative 120, 0, 0, 120, negative 120 something like that so a sequence of angles, or turns, and you send that sequence through the string.

It's 20 degrees outside.

It's six degrees below zero.

The water is completely black.

The thermometer registered minus ten last night.

Fresh water freezes at zero.

Minus five degrees, straight 45 degrees. This is the range for what?

So this is going to be I'll do it in a different color 180 minus 88.

The measures of the interior angles of a pentagon are 2x, 6x, 4x minus 6, 2x minus 16, and 6x plus 2.

The second one is, how do you go to the loo at minus 40?

And then you have to store them at about minus 20 degrees C that's about minus four Fahrenheit, I think with a very critically low moisture content.

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

If we assume that it's one third, then indeed we recover the pendance of radiation energy density as scale factor two 4.

It is indeed, but the ocean is liquid methane the temperature minus 170 degrees centigrade.

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

The measure of angle one is equal to 80 minus 40 is 40, so 80 minus 46 is equal to 34 degrees.

And then the next month you're going to come back and you're going to pay this 1,200 again.

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.
