Grade 7th on Khan Academy: 7th grade takes much of what you learned in 6th grade to an entirely new level. In particular, you'll now learn to do everything with negative numbers (we're talking everything--adding, subtracting, multiplying, dividing, fractions, decimals... everything!). You'll also take your algebraic skills to new heights by tackling two-step equations. 7th grade is also when you start thinking about probability (which is super important for realizing that casinos and lotteries are really just ways of taking money away from people who don't know probability) and dig deeper into the world of data and statistics. Onward! (Content was selected for this grade level based on a typical curriculum in the United States.)

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

I just relearned long division after 40-something years.

...the second time I watched this.

[nadeemnoor]

This video is very helpful for me and all people

[maajidahmed]

That was really good information thank you so much

[veelavon]

This is a strange problem. Either it doesn't make any sense in the real world, or I'm missing something. I paused the video and had the result figured out very quickly but thought I was wrong so I got stuck for quite a bit. In the real world, when you buy something to sell in your shop, you immediately get back what you spent, + the margin you put on the product (here, 27$). You don't spend $10000 on computers and just expect that the money is "lost" : the point is to get back the money as fast as possible and as surely as possible. I was absolutely certain that the result would be something between 10 and 20 computers to make sense so I thought some information was definitely missing. Who in their right mind would sell computers at $0 a piece ?
