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!

Thank you so much! I was having trouble since over the summer I had forgotten about a bit of standard algorithm, and this seriously helped. Subscribed in case I ever need more math help!

[joannahart]

this did actually make it make a lot more sense

Thank you SO much! I'm in sixth grade and is studying chemistry, physics, calculus, etc. I can name tons of unheard of polygons in geometry, and all of that, but we have been learning decimals and I didn't understand at all. Heck, I can't even long divide for some reason. This was the only thing that made me understand, and now I can do good on my test tomorrow. :D

Also my teacher: doesnt tell me the stuff I dont know and will need.
This guy: Explains everything so perfectly including the stuff I didnt know like a an actual teacher should

All you actually have to do is divide 5005 and 7 then when you get your answer (715) you move the decimal point from the actual decimal but you have to figure out where, well since their are 3 digits beside (from the right) of the decimal the you have to move the decimal 3 times from the left on the answer of 5005/7 and that is 715 so when moving the decimal 3 times to the left you’ll get .715, i hope that helps if you dont get long division with decimals and whole numbers like me

-this is from a 12 year old

I seriously don't understand the point of Division and Dividing decimals. We're not going to use it any time sooner in our life when we're adults so I really don't understand.
