At the end of this process, we have a mixed class='bold'>class='bold'>plastic composite many different types of class='bold'>class='bold'>plastics and many different grades of class='bold'>class='bold'>plastics.

And in the process, we started recreating how the class='bold'>class='bold'>plastics industry makes class='bold'>class='bold'>plastics.

i have a cap from class='bold'>class='bold'>plastic

class='bold'>class='bold'>Plastic does not burn easily.

class='bold'>class='bold'>Plastic does not break easily.

Our class='bold'>class='bold'>plastic has become their diet.

And that's a class='bold'>class='bold'>plastic polymer.

Row 2 minus row 1.

So the second row minus the first row.

Just replace this row with this row plus the first row.

Let's replace this row with this row minus 2 times that row.

Let me replace the second row with 2 times the first row minus the second row.

And then row 2 minus row 1.

The third row minus 3 times the first row.

Capt. Charles Moore on the seas of class='bold'>class='bold'>plastic

They store the class='bold'>class='bold'>plastics on the roofs.

class='bold'>class='bold'>Plastic is so permanent, so indestructible.

They are integral to our modern day lifestyle.

class='bold'>class='bold'>Plastic just is not going to do it.

I just basically gnawed all this stuff out of class='bold'>class='bold'>plastic.

They're class='bold'>class='bold'>plastic they last and last.

Well, this was one row, and this is the second row, this is the third row, and this is the fourth row.

It's the third row minus 3 times the first row.

This row is the same as this row.

And I didn't touch on it in that video, but there is also such a thing as a lower triangular, that you might have guessed how it looks.

And let's replace our second row with the second row minus the first row.

Mike Biddle We can recycle class='bold'>class='bold'>plastic

And this becomes the currency of the class='bold'>class='bold'>plastics industry.

class='bold'>class='bold'>Plastics are also hard to recycle.

The world of class='bold'>class='bold'>plastics is present everywhere.

Now look at that class='bold'>class='bold'>plastic chair.

People use class='bold'>class='bold'>plastic everywhere.

What I could do is I can replace this row with this row minus this row.

So what's the third row minus the first row?

I'm going to subtract 2 times row two from row three.

Get in a line, lady, get in a line please.

Class

Row

And these are just a few examples of companies that are buying our class='bold'>class='bold'>plastic, replacing virgin class='bold'>class='bold'>plastic, to make their new products.

So I'm replacing the top row with the top row minus the third row.

And let's replace my first row with the first row plus the second row.

I'm replacing the first row with the first row minus the second row.

And let me replace this last row with the last row minus the middle row.

Because this row, row 1, column 2.

So the first row well, I won't even write the first row.
