I am failing math currently, and you explained it way better then my teacher. Made it sound more logicial!

[@bruvtalk9348]

DA MOSHUNZ honestly

[@colossalc5219]

You're probably failing Language Arts too. Than* Lol I'm kidding

[@animegirl2245]

It is really simple. My advice, I know your post was a while ago, but watch multiple videos.

[@aidenshimodaira8919]

try watching videos on linear inequalities, and if that is too hard, simply watch a video on inequalities and then climb the ladder.

[@abdalrhmansalman7225]

Welp u r the problem here mate :/

[@chloegreen8827]

This man teaches a lesson in 11 minutes but it takes our teachers an hour or more for a few days

i could learn more on khan academy more then the entire school year

Because this video clip doesn't need to interact anyone and you can replay it infinitely.

i swear, this almost 12 min video just saved my life, i have the worse math teacher ever, he is a nice guy but does not teach anything in class, this video actually helped me to get the problem. thank you SK.

You’d be paying an incredibly large sum of money to get someone like him to tutor you. It’s great that he is able to share his educating experience with students for free.

I have the worst math teacher ever because he always goes too fast and that makes it so difficult. When I go on Khan Academy, I understand it so much and I actually LEARN HOW TO DO IT! THANK YOU KHN ACADEMY!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

Omg I’m understanding and not afraid of my test yesssss

Your way at solving these is so much easier than my teacher's way

I like how you go through all of the steps, no matter how elementary they are.

he didnt do interval notation for the last one and thats the one i had a question about !!!!!

[@iswim4brighterdays]

I love how I learn more in 12 minutes on KZbin than I do in 40 minutes with my algebra teacher

[@Braeden123698745]

Thats because in class... Teacher: "Does 2+2=4?" Class: "..." 15 min later Teacher: "Yes, yes it does..."

[@Lanon0987654321]

I know how to do the process but when I try to do some practicing at the app I get everything wrong I am missing something

[@goldenguras]

Thank you. I was having a confusion on the two equality equation. Solved it very simple and logically by separating the equation and arriving at the answer.

[@cora1078]

I'm wondering how you fix the equation when a number x isn't in the middle. Do I need to make anything negative? I can't find anything on the internet about it and my teacher never taught it to me.

[@paulvalencia6219]

Now I kind of get it. I am going to watch a few more times until I become good at it! Thank you very much!!!!!

[@MB_Tyres58]

Thank you so much I needed this for my exam tomorrow and you helped with this and now I will deffo pass the exam InshaAllah

I love my math teacher and all, but sometimes she hard to understand, and inequalities aren't that easy for me. You explain it so well, and I cant thank you enough

I have a math test tomorrow and i literally dont understand how any of these work until i found this video:) Thanks!

[@jacobbob09]

I was sick when the teacher went over this in class, so I wasn't there. She just told me to learn it out of the textbook. That didn't work as I am an auditory learner. This video helped so much! I'm going to show her these videos so that she can either show them in class, or take some inspiration from them.

[@BatmanEditzzzz]

A video made thirteen years ago saving me rn fr 🙏

This man make everything look so easy and fun like i actually found interest in math cause o dis vid

[@onelasvegas]

I was so lost But, I am so happy I found you. I now have a understanding on how to solve. thank you

[@OnilVelez]

how do u know when to multiply subtract or divide or even add when solving or even startingany problem

[@furiosscout5239]

For the last problem, you could multiply by 2 and then divide by 9, that also got me 6/9 or 2/3

[@damoshunz2535]

So when do you swap the signs? Only if you divide by a negative number? Someone explain and how did you get the 2 and 4/5

[@hilldoesmc]

You swap the signs when you divide or multiply ONLY by a negative number and he just turned the improper fraction into a mixed # its the same thing still

[@kylannaidoo4141]

+DA MOSHUNZ u switch the sin when u divide or multiply by a negative number

[@Rike1917]

"lets do this side of the equation in green.... lets do this side of the equation in green..." "what would that look like on a number line... on a number line..." "Lets do another one... Lets do another one..." lols... i love this vid! i totally understand how to do this now! thanks!

[@LuminusGaming]

And also §

[@nabeehakhan555]

Very helpful

[@zachmohl]

At 5:14 I think you accidentally subtracted 2 instead of adding it. You do the opposite of what's in the inequality and since it's all subtraction you would add 2 and get 10.

so do you always switch the inequalities when you divide by a negative number?

yes and when you multiply by a negative number

for the "OR" problems do we have to do both sides or can we do just one?

Both

[@jennivanmarchan7799]

Then what was the interval in the last equation? None?

[@matthewyoung5155]

Thank you

[@caleblantrip4955]

This dude 100% better than my teacher

[@weevo_gg]

I may have misunderstood, but I thought when you multiply or divide across the inequality, you have to reverse them? so the left side should have the symbol flipped?

John Coulter do the opposite

[@Anonymous-tx2qs]

Best teacher ever!!!!! By the way you messed up. You said 13+14=17

[@purojays]

Why wasn't the sign swapped at 9:46 when dividing by 4? Can someone pls enlighten me.

[@sdasilva76]

From what I understand, you only swap the sign when you're dividing by a negative number.

[@animegirl2245]

Also, may I just point out that if you are in college/university, they do not do this method. You will not use open or closed circles. However, it depends on the college/university. They teach brackets and parentheses instead of the circles.

[@eyadfamilyhajomar4933]

thanks this helped me alot!!!! but u got mixed up and said 13 +14 instead of 13+4 bro
