Adding and subtracting negative numbers | Pre-Algebra | Khan Academy 

Taught this better than my teacher did..

It's not how your a genius at math it is about how you can draw so well on a computer

You are the greatest mathematician with golden heart to help everyone for free! Thank you Salman Khan

This guy is a life saver, I have an awful tutor and they explain stuff really badly and my teacher kind of skims over this very quickly so this video is amazing :)

if you wrote all that with a mouse, your really good at it, unlike me. but anyways, thanks for your tutorial :)

Thank you so much for this, totally flashed back my memory, need this for my assessment.

When You realise he is better than ur math teacher..

I have a math test just like this tomorrow thank you for helping me understand it!!!!

Thank you I really needed this for my test

This is the best mathmatition

when instead of studying for your tests you just watch videos to help remember stuff smart 100

thanks so much i just started 7th grade algebra this will help a lot

Me after listening to my teacher FrIed BrAiN Me after watching a video on Khan Academy BIG BRAIN-

the number line strategy is so much easier 😊😊😊✌

Thanks this really helped, the teacher will make this simple thing so long and hard.

thank you,it brought back my memory for my selective enrolment test

Yes I was confused I never practice now I saw this video and a practiced this now it's stayed in my brain for around a few months from now 😊😊😊😄😄😄🤓

So I'm a 6th grader with 6th and 7th grade classes. Thank you so much for making this, because I forgot some of the things I did in math in 5th grade, or I didn't do the lesson because I was REALLY lazy. Anyway thank you, because I really needed it. c:

Its embarrassing for me cuz I'm in algebra 2 and I still find it difficult to add and subtract certain negative numbers sometimes (especially on no calculator tests) so thank you for this

My Gahd This is very useful to my Exams! Wish me luck guys

All my math teacher does is talk about his life and how is such a " great" teacher when he is like 78 years old

wow youtube teachers like you are super amazing than school teachers

ou are the greatest mathematician with golden heart to help everyone for free! Thank you Salman Khan

He is so good in explaining and even can explain better than my teacher

I learned a lot from this video.Thank you Khan Academy 😀😀

this is so great!!!!!

Is he low key the bob ross of math?!

You are just the freaking best ! ! !

We are learning this for 6th grade math and I don’t understand a thing. Tysm for helping me understand a bit

Is there a video explaining how to add and subtract 2 negative numbers?

Omg!!!! The best way to explain this. I wish I had someone explain it this way when I was in high school and college. I am trying to pass my Praxis and this is so very helpful. Thank you so much Sal 😁

Wow he rights so good on the computer

Thanks man I am in year 6 I have a test tomorrow this helped

Thanks now I can do well in my exams

THIS IS SO HELPFUL THANK YOU😤😤

This really helped (if you like this, you will ace every single test)

How is your writing LITERALLY legendary?

so why does a negative equal a positive in that case?

THANK YOU!

Thank you so much. This was so confusing!

THANK YOU FOR THIS VIDEO! My teacher explained this so badly, only from this i understood this, thank you again

this helps me a lot

You are my idol! Thank for inspiring me =)

Thank you it work a lot because I need it more review

can you explain the rules of multiplying and dividing integers?

Explained it better than my math teacher lol

On go math they give me 5 ways and I don't get anything from it but the number line I think is the best

i "learned" this in my pre algebra class, i am now in geometry 2-3 years later reviewing how to do this bec sal teaches this better then my pre algebra teacher ever did and i was always too ashamed to ask all my other math teachers how to do this oh goodness

Is this guy on like some next gen mouse/touch pad?

WHEN YOU RELISED THAT HE IS BETTER THAN YOUR SCHOOL TEACHER 😂😂 LIKE IF YOU AGREE 🐹

Thank you...

hi can you explain 2-(-3) = 5 on a number line?

what kind of program do you use for drawing the problems

Thank you

Thank you, now back to my hw

Thanks I am going to sixth grade and this will help through my life again thank you

The More You Learn!

I've been watching all videos about integers in the internet but it still can't go in my brain

You are still better than my teacher in 2020

What program do you use for the drawing/writing in these videos?

This is very helpful we are learning about this in school right now

But how is negative 2 minus negative 3 negative 5 my calculator says 3

Thanks sir 👍👍👍

cool

Ya true.Our math teacher knows only for himself.He gives classwork ,homework.Too boring😑 I didnt learn anything from him.I got help from my parents and khan academy😚😚😚😚😚😚😚😚

Nice khan academy

How did I get here

Good job on the vid but what if you can not make a number line?

thank you for that you was a goog and nice teacher

Thanks😊

Nice

Thx your way better than mathantics

i can't figure out if he's using a mouse or drawing tablet, like what

I understand now thank u a lot

what app are you using?

thanks for this help

THXX FOR THE HELP KHAN ACADEMY

Thanks

I was with you until 2-(-3)=5. Why don't you represent this on the line? How does this apply in real life? Please give an example thereof. Thanks

Can the problem be 2-3 and still equal 1 without having it a negative, or is it a universal rule that the bigger goes first in subtraction? I always thought to take from the bigger number. Could you explain

Tip: If you are adding and the sings are the different you can add them together to get your answer and then see which number has the greatest integer

1:39 something wrong! -2-3 is 5! It is in the rule of integers

Super helpfull

it was very very helpful

you are the best

People that think that this video explains it really well 👇

Very helpfull

Thanks for the help Salman khan

thanks for that

Hi...

Cool!

Excuse me which is greater a positive minus negative or negative minus positive? 🙂

⭐😍حلووو عبقري

This didn’t help me though. I have to know and be able to explain a problem similar to -2 - (-3) without changing the problem to -2 + 3. This “rule” doesn’t explain the “why” and that’s where I’m struggling.

My friend's last name is Khan. Shaik Khan.

sure

I need an explanation on the 2- -3. It's not enough for me to know that the minus becomes a plus and the negative becomes a positive. I need the why explanation if anyone can link the video or explain.

What is the software you use?

The way I like to think about adding negative and positive is a bank account and let's and I know I am in your dept

How do u subtract negative number without number line
