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!

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.

These videos are the only ones that can say things in a way I can understand...I'm going back to school for my RN and I'm old and suck at math lol so thank you so much

You need a freaking Academy Award for this amazing video. Not only did you bring up Googool, you mentioned your lovely wife and her attention to detail about adding a zero in front of decimals... I have clarity now! Last night I dreamt that the whole world had scientific notation as directions. My Ram truck dashboard read: "Speed six to the 10" and my Amazon orders was 1 to the negative tenth and I owed PayPal money in the negative tenths and so on. Today I will just ride my fat tire bike and forget about it for a while. Your cursive writing is APLUS... Like clouds in a world of ordered chaos. What will your Academy Award speech be about.? ? "" ? I hope world peace, because you are the only way out of this mess EG summation, No ads, No ads, clarity, nice voice, and you are helping some girl in Afghanistan bring about peace in her time. This can be proven with scientific notation Zero to the negative tenth times one is at least a chance.
