From time to time we like to let you know about any changes we’re making to keep our site up to date. We encourage you to check out our Terms of Service here but here’s a simple overview of the main changes:
We wanted to clarify which content is available under a creative commons license (e.g. videos made by Khan Academy) and which is not (e.g. videos from some partners) so we updated the terms to make it clear how that information will be flagged
We wanted to make what we mean by ‘non-commercial use’ clearer so we added more explanation and examples
We wanted to clarify how child accounts can gain parent approval before becoming operational
If you have any questions about these updates, you can email us at firstname.lastname@example.org.
Thanks for using Khan Academy!

Two billion, nine hundred ninety-nine million, nine hundred ninety-nine thousand, nine hundred ninety-nine…

We celebrated with cake pops in the shape of a big 3, making the day all the sweeter…
Today’s an exciting day for us – together we’ve just hit the 3 billionth problem answered on Khan Academy!
We asked Sal what he thought of this, and he said, “Personally, I don’t know what all the fuss is about. I’m waiting for us to hit 3 141 592 653 problems solved before I get really excited.” Can you help us get to pi billion?!
The rate at which everyone is learning on Khan Academy is astounding: it took less than a year to grow from 2 billion to 3 billion problems answered! Way to go!
And just how big is 3 billion, exactly? We did some digging …
- If you had a measuring tape that was 3 billion inches long, it would wrap around the world twice.
- If you traveled a mile for every problem that’s been answered, you’d almost be at Pluto.
- If you went back in time 3 billion minutes, it’d be the 37th century B.C.E., a thousand years before the Egyptian pyramids were built.
Whoa, that’s a lot of learning.
So… how quickly can we get to 4 billion? Let’s go!

In little more than a year, we’ve been very fortunate to collaborate with numerous institutions of incredible caliber and expertise, such as The British Museum, Tate, MoMA and The Getty. Their content on Khan Academy has gotten hundreds of thousands of views and we’re constantly hearing from our learners, whether they’re studying for a class or just nerding out on art and its history, how valuable the tutorials are; last year, there were 7 million visits to our art history content alone!
Today we’re very excited to welcome The Metropolitan Museum of Art to Khan Academy. As life-long New Yorkers, we visit the Met at every chance we get. You could say without exaggerating that we learned how to look at art in the Met’s glorious galleries (and in fact we both wrote our very first respective museum papers on works in the Greek and Roman collection!).
Today, the Met launches over 100 videos on Khan Academy featuring areas such as Extravagant Inventions, Books, Music and Literature and Devotion. In addition, The Met will also feature a game focused on the permanent collection, Beyond Battle: Arms and Armor at the Met.
You’ll also notice today that we’re grouping all museums on Khan Academy on their own landing page: now you can find our museum partners (including the Asian Art Museum, the American Museum of Natural History, Exploratorium, and the California Academy of Sciences) all in one location. We can’t wait to hear what you think.

Our friends in Brazil, the Lemann Foundation, recently asked some twenty celebrities about their favorite way to learn math, and they shared some really touching thoughts about Khan Academy and why they love using it. We thought it would be fun to share them with you, too.
Bill Gates, for instance, stressed the fact that Khan Academy is a great tool for one`s learning adventure, saying that the “breath of stuff is incredible and the explanations are clear”. He also pointed out that he uses Khan Academy to remind himself about certain concepts and with his kids “when things are complicated for them” - which makes us feel better about forgetting things, too!
This year, over two million Brazilians used Khan Academy to study and learn - we’re so excited that they’re enjoying the Portuguese site.
O que Bill Gates, Anitta e Anderson Silva têm em comum?
A equipe responsável pela Khan Academy no Brasil recentemente perguntou para mais de 20 celebridades do mundo da música, das artes e do entretenimento sobre sua maneira favorita de estudar matemática e eles compartilharam os benefícios de estudar com a Khan Academy de forma gratuita e empolgante. O grupo inclui ídolos nacionais e internacionais, como Bill Gates, a cantora Anitta e o campeão de MMA Anderson Silva. Aqui você pode ver alguns desses vídeos.
O Bill Gates, por exemplo, falou que o site é uma excelente ferramenta na aventura do conhecimento - “a quantidade de conteúdo é incrível, as explicações são simples”. Ele apontou que tem acessado a Khan para se lembrar de alguns conceitos e que seus filhos também usam “quando têm alguma dificuldade” – o que nos faz sentir melhor quanto esquecemos as coisas também!
Esse ano já são mais de dois milhões de brasileiros estudando e aprendendo com a Khan Academy! Estamos super entusiasmados com o sucesso do site no Brasil!

I often get asked how I got into programming. Well, it all started with me forgetting to buy a gift for my mum. I was in 6th grade, and it was Mother’s Day. We lived a few hours walk from the shops in town, and I had to walk by a high-security penitentiary to get to those shops - given the recent surge in prison escapes, I didn’t feel like taking the risk.
I’d been browsing the web a lot recently, checking out the fan websites for my favorite boy bands and hanging out in pet-themed chat rooms. I always liked the idea of making gifts instead of buying gifts, so I thought “hey, I’ll make my mum a webpage!”
I searched on Yahoo! for instructions (this was even before the days of Google'ing), and made a webpage for my mum with a big cheesy “Happy Mother’s Day” GIF at the top (thanks, Microsoft Word Art!). My mum was happy that I’d taken the effort to learn something new; I was happy that I’d discovered how to get away with never buying gifts and I was left with a newfound curiosity for making things on the web.
That’s why I’m thrilled that we can now teach HTML and CSS on Khan Academy. HTML/CSS is the first step on the path to being a web developer, plus it’s also a skill that non-developers can hugely benefit from - like bloggers, marketers, and librarians - because HTML shows up in so many of their jobs, too.
To help you learn how to make webpages, we’ve put together an Intro to HTML/CSS course. It’s around 8 hours of talk-throughs, coding challenges, projects, and quizzes, and will give you a great basis in the most common HTML tags and a wide range of CSS selectors and properties.
Thank you to the team for all their hard work in making this possible - John Resig, Brian Bondy, and Alex Rodrigues. Let’s get more people hooked on HTML!
