Let, let me move on.

Let me count them.

Allow me to introduce...

Let me switch colors.

So let me clear this.

Let me tell you

Let me swap the labels.

Let me erase this.

So let me switch colors arbitrarily.

let me ask you a question.

Let me ask you a question.

Let me write that.

At this point I decided to make a pause.

Now let me ask you a question.

So let me just take the calculator out.

Allow me to sell you a couple?'

And let me do another example

Now, let me tell you,

Let me close my window.

So let me tell you a story.

Let's do a harder one.

Let me clean it up a little bit.

So let me give you an example.

Let me do it in a completely new color.

Actually let me do that.

So let me write it over here.

So let me try to redraw the curve.

Let me do that in a different color.

So let me put it this way.

This is equal to let's switch colors.

let me do it in a different color.

So let me rewrite this expression.

Let me show you what these people do.

So let's say I have a triangle. Let me draw it. Let's say I have a triangle that looks something like this.

Let's say that this value right here is... I don't know 3.

Let's say let me pick some random numbers

And so then let me just draw these dividers.

I didn't draw that well, let me give that another shot.

So let's factor out (let me use a different color)

So let's see Let me do a different color.

Let me erase some of this stuff that I've written.

So let me just draw you some more odd functions.

Let's say that let me switch colors just to not be monotonous.

Let me say it's a mapping from R2 to R.

You see, what you need to understand... Let me put it this way.
