This is honestly easy, but the thing is, our teacher likes to take away variables or make it confusing during tests. The examples he gives are easy, but the quizzes makes me want to bang my head on the wall.

[Zay]

Math is only hard when the teacher fails to teach.

[joshanesxd]

You need to teach my teacher how to teach

Bruh I see all 8th grades here and I'm a junior 😳 that has a quiz tommrow

Edit: currently unemployed life is way harder than equations
Edit recent: Returned to GOD working and studying a course keep going its possible💪

What he teaches in 10 minutes, takes my teacher over and hour to teach, and I end up learning more from the vid

My teacher likes to go through each equation like it’s a speed run, which is hard for me to differentiate how to do each specific equation the correct way, much less I have a hard time learning with his style, so this video is a life changer

Have a test tonight and was having trouble understanding these math concepts, your video made it easy to understand. Thanks

I've been really struggling with substitution in my 8th grade math class right now, and I think I'm finally getting a grasp on how to do it! I used to dread the days we'd do substitution. I still love elimination a lot more, but my anxiety has been getting worse with the stress of not understanding substitution and I really think it's clicking in my brain now! You're a life saver - thank you!!

this guy rlly taught me more in 10 minutes than my math teacher has taught me in 3 months

edit: I was the only kid who got 100% on my test tysm

I haven’t been in school for ~8 years and I’m studying really hard to score well on my ASVAB for the air national guard. You have helped me TREMENDOUSLY with stuff I had long forgotten about and are getting the cobwebs off of my brain. Seriously thank you so much.

[anika]

this 10 minute video taught me more than a 50 minute algebra lesson smh

[justinherb]

Just gonna say, if it wasn't for these videos, I would have already failed college.

[Ana.is.sad.]

I can't pay attention in school so you are literally the only reason I'm passing 7th grade math‼️

[jordanzart]

This is waaaay better than my curriculum, thank you so much. My teacher goes way too fast and there isn't a pause for me to really grasp the ins and outs of each concept. He only gives one or two examples and I rarely understand it.. This helps a ton, thank you🙏

[klondiek]

My old math teacher used to say "Math is easy, people make it hard." This truly proves him right.

[ericakoenegstein]

I literally act like I'm taking notes in class and then come take notes from these videos. It's SO MUCH EASIER!

[craigvaughan]

Thank you, my math teacher complicates things and I hate it

[Omgitsball]

I have a test tomorrow on this anddd this helped me understand thank you so much!! 💚

[eclipseaaterminator]

Thx for no long intros and just getting straight to the math. I don’t have time for that kinda stuff
