Multiplying decimals? Try multiplying without the decimals first, them add them back in. We'll show you.

Missed the previous lesson?

Pre-Algebra on Khan Academy: No way, this isn't your run of the mill arithmetic. This is Pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We're about to take off!

For free. For everyone. Forever. #YouCanLearnAnything

This is what happens when you're used of using calculators and then the teacher announces that no calculators allowed in the exam. I HAD COMPLETELY FORGOTTEN HOW TO WORK WITH DECIMALS POINTS. So thank you so much for this, you make everything so clear and simple. I will not fail my exam now :)

Thank you Khan Academy!! 😭😭😭 I’m 23 years old and have NEVER been strong at math, and all my teachers growing up in school here in California never wanted to take the time and REALLY TEACH ME, One on One so I grew up with a HUGE insecurity and fear of math. But that’s negatively affected my job hunt and now I’m on the prowl to re-learn what I didn’t understand growing up, and you guys are FANTASTIC!!! Thank you again! Keep up the amazing work 😊😘🤩👏🏾
