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.

When I was 2-_-

I was 2
Me: this is probably the level of difficulty I need to watch *starts video*
Khan: and this dot means multiply
Me: *leaves*
Maybe its because some countries use X and not the dot?
Eternity Quartz no, the dot is just more formal then the x
@@lazydreamer7745 I never really understood why we use Dot amd not X so thanks for telling me ^^
Lmao right. I just kept watching cause I gotta cram all the info into my head before finals in a few weeks.
We use the dot because x is used as a variable a lot
I'm not learning this. Too busy going through comments.
Me too
pspkider Same lol
I think what makes Khan Academy's videos better than other math videos is the silly unintentional mistakes he makes while writing the equations XDDDD.
2:19 "I hope I achieved my goal of confusing you just now"
*"LeTs dO aNoThEr"*
Haha :D
i am learning this again, in my freshman year of college.
wow, im currently a freshman, any tips? 😂

This helped me a lot! I had problems with this cause my teacher couldn't explain it right. Thank you for this video!!!!!!!!!! Who ever the speaker is..... he my hero in math! LOVE YOU SPEAKER!!!!
I wasn't born when this was uploaded
oml same
that is so sad
what are you like 10?
same
Oof, man.
Amen FlashBright, I'm gearing up to take the GREs to get into grad school for ART, and I want a good score. Unfortunately I haven't done math in seven years, thanks to these lessons it's all coming back to me so I can actually start studying!
When you show me something that I had once been taught and have forgotten, it’s like finding a pot of gold in my brain. The pleasure of unlocking something that you were once familiar with is a gift. You are entertaining as well, thank you.
watching this rn before my quiz gl to me XDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD

Hope you passed!
yeet
lmao 4 years later how’d it go?
After a long summer break, this video was a literal lifesaver as I had a math summer assignment that is thankfully due later in September. Thank you!
Thank you for uploading this video khan academy because next week, I have a quarterly exam..and of course math is also one of the test ...so you were a big help...Thanks (Y)
This video was uploaded when I was not born.i was born in 2009 this video is from 2007 when TH-cam came up
I'm being forced to watch this

This was uploaded before I was even born!!! Now I needed it!!!

Help me im forced to watch this by my mom/teacher
SAME the tortured

TH-cam Golden rip my dude
I remember watching this in grade 8 when I struggled in math, now I’m watching it again as I’m going to be tutoring a grade 8!
It's obvious that Sal is great at math, but I think he could benefit from learning some basic teaching strategies. The academies system works best as refreshers after being taught by a licensed teacher.
Thanks, your method of teaching is helping me with algebra. I'm in culinary school where it is much needed. I never took it in junior or high school. So now I cannot escape! 😱😊 U r the best!!
it is? i thought in culinary the majority of the time fractions are involved..
THANK YOU!!!!!!! you will help me through
school!
This helps me so much, thank you!
Thanks Khan Academy you explain more than my math teacher
Sal, I like your teaching very much, keep up the great work and I'm mean it.
thanks i aced my test☺☺☺
Qudsia Khan next lets look at quizlet for answers 😆
okay I get the multiplying and dividing. But I'm struggling with subtracting exponents with same base. Am I supposed to change it to a division or multiplying equation somehow. 😭😭😭😭😭😭
U would have to do the exponents then add then together
I'm learning this in college. Beat that!
Thank you for all of your instructions, I am actually learning this...you're good at this teaching thing=))).
Thanks for posting!, very helpful.
youre old (:
Yeh
this came out when i was born and now im watching it thank you
Thank you- The struggle is real.
Your one of the best math teachers I’ve seen.
lmao im in 8th grade rn, this is for me too look back on 5 years from now
WrongDirectorTV yassss same
Huge help thanks
wow thanks now i dont get confused by this stuff!
Bro this really helped me out. *I hate math*
i learned more in under 10 minutes than 2 days...
I know this video is old and all but ever since like the age of 10 I've looked up khan academy if I get confused with math homework so Thanks Khan Academy
Which program did you use to write characters?
Joe Verzino Old version Powerpoint nor paint????
idroo
I’m just watching this to know the name of the terms in English...Thank you 🌝💕👌🏼
Josiah-you really broke this down for me
thank you so much
to times to times to times to times to times to times
Laws of exponents are really useful when dealing with decimal numbers!
Yall hear that sniff at around 1 minute or so. Lol im dead😂😂
Breh focus on what you are learning not the sniffing

thanks it helped alot
Thanks bro I am haveing problembs with this (8th grade)
So having a negative exponent is acceptable.
Thanks!
Reciprocal only.
in 5th grade we did this and now when i come to 6th grade the first thing is exponets and order of operations. thx i needed help on this alot so thx :3
thx for thx video i been useing you website for a long long time this video saved me i will donate ur website 5$
great explaining
Oh my god I hate school. This guys cool, but my mom forced me here. I do the damn math and my dad checks it, changes it around and screws up my grade. Then I get yelled at for it and now I can't watch Smosh, Pewdiepie, or play Animal Crossing. I would like to dedicate this lovely message to my parents, and my lovely retarded school. I love this generation.
I have final in math tomorrow morning wish me luck by the way this is helping a lot
love this omg
thanks, it helped me
I'm even more confused
3:36 "just want to give you a little bit of a warning" don't know why but I love that part ^w^
Anyone watching in 2019
Gok Gaming nah 2020
I'm watching it in 2020
thank you so much you helped me become a achiever!this is really awesome!!!
i see you korean
good teaching thanks it is help ful to us
Thanks so much kinda forgot
thank youu!
khann academy vs math antics both really good
this was very helpful
Thnks
im sorry but can you explain how is 2.2.2=8 because i thought it were 6 i dont get it
Dawnesha Haugabook 2+2+2 = 6 however 2x2x2 is 8 because 2x2=4 and 4x2 = 8 which is 2 to the power of 3
What if we have a negative exponent for the numerator and a positive exponent on the denominator? Do we still do the same?
I understand this without u but really ur making it more complicated than it really is
i love this guy
What do you mean by "There's 2 to the 8 times 1, 2 to the 8 times 2." at 4:33?
well i love the videos they help me learn a bit and review it
and im only 10
This video was made when I was 4😳 no I’m 17 at it’s helping so much😭❤️
Bro, in just one week I’ll be entering my Pre-AP 8th grade year and I’m trying to study this 9th grade stuff just to get ahead and have an idea of what we’re going to be learning. This is so complicated (´༎ຶོρ༎ຶོ`)
@FlashBright college math? i gotta learn this in grade 9! :( but Sal helped me out and i owe him my 100 marks!
Our teacher’s making us watch this because he said he’s gonna take it up next class and i am in complete confusion 🤩
yes you have achieved the confusing the watchers
I was 3 years old when you uploaded this video
I remember when I was taking pre college level algebra. And I had to always wonder what the difference was. I guess it has something to do with multiplying. The parentheses always are like that. I get the concept, however I still have to wonder what the whole deal is. I could teach it to people and get by, however I think that requires A PhD person. And they would totally confuse you. At least that's my opinion.
this is helpful
So when would the average person use this in real life?
@juanarruti unless otherwise specified with parantheses, it is the first one
Thx so much
Holy crap, this was a year after I was born😂I have a REALLY important test tomorrow, I’m in 6th grade I’m 11, and with this test, it’s like, make this test, or don’t go to middle school, I love Kahn Academy
