And that notation is Sigma notation.

It's just all notation there's nothing particular about notation.

Sigma notation up.

This is another notation.

I always forget notation.

Yeah, see that notation?

And I'll introduce my notation.

This is just my notation.

I'm just making up notation.

These are all equivalent notation.

I'll use the same notation.

This is just different notation.

We've seen this notation before.

And the notation is PV

Very, very specific encrypted notation.

And it's a very subtle notation.

Write your answer using exponential notation.

This is just a Leibniz notation.

That's what this sigma notation is.

This is, I believe, Leibniz's notation.

I have all the sigma notation.

This is just notation right here

Prime factorization, and they say exponential notation.

We'll worry about the exponential notation later.

This is just the notation they use.

Let me write it in set notation.

I shouldn't be lazy with my notation.

And how do you use Sigma notation?

And this is a very unconventional notation.

Let me just write our formal notation.

Maybe I should put a vector notation.

If I wanted more traditional function notation

Make sure we get our notation right.

If I wanted to write that notation.

And here we've written something in kind of an exponential notation, or we should say scientific notation actually.
