I'm the founder and faculty of the Khan Academy,

and we're trying to educate the world.

Welcome to the presentation on basic addition.

In August of 1789, they've already

done their version of the Declaration of Independence.

The process is called photosynthesis.

I was tutoring my cousins, literally,

and I had to figure out a way to scale myself up.

So I started recording YouTube videos,

and I started making little software modules for them.

But I made it so anyone could use them

and started getting a lot of traction.

BILL GATES: What Sal Khan has done is amazing.

He's taken all this material, and broken them down

into little 12-minute lectures.

I use it myself to remind myself of things.

I have children who like it.

So I was super happy he came up, and we

got to talk about where does he go now?

How can my foundation help him pursue this dream

and connect it up with the other great things going on

in the internet?

SALMAN KHAN: I want it to be a standalone virtual school where

anyone in the world who wants to learn anything

can go there, start from the basics,

progress as far as they need to go,

get feedback, get assessment, get practice.

And eventually I want it to actually become the operating

system for what goes on in the classroom, where

every student's allowed to work at their own pace,

and the teacher actually becomes more of a mentor or a coach.

BILL GATES: So I see Sal Khan as a pioneer

in an overall movement to use technology

to let more and more people learn things, know

where they stand.

It's the start of a revolution.

SALMAN KHAN: All of the videos, they're all free.

Openly accessible.
