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!

I am 32 and I had a hard time learning math because of my ADHD if you are reading this, it's not too late to learn math. Thank you Khan because of these videos I was able to pass my real estate license because how weird the calculations they shown. Your videos gave me a huge boost of self-confidence to pass.

What a great way to start kids off to learning exponents... we enjoy all of your videos: I bet other children wish they could have a teacher just like you. If children know how to do multiplication and division, they'll get the concept of this quickly. Thank you.
