Algebraic Equations and Their Solutions

[@sneakyboii732]

I have a very poor understanding of the basics of math, as I was a very lazy person throughout my general school days, and my very first 2 years of high school, but after that much time passing I realized I had made a grave mistake, and learned only the advanced stuff, but nevertheless, I made it through high school and I was desperate to find somewhere to learn the basics, and here I am. Thank you very much, for doing these kinds of videos

[@superstellarrr]

i relate to this sm TT hope u are doing well now !!

[@Kitcat_myce]

same problem, man..

[@convoy4298]

i have a horrible math teacher this year and this helps me more than you will ever know, thank you professor dave

[@derby9195]

You're a gift from God for people with dyscalculia like me. This is the first time I actually understood how to solve algebraic equations. I wish more math teachers teach the way you teach. Thanks professor Dave!

[@yuugi5185]

Its the 6th day of learning math and my brain is cooked very well enough to be eaten by professor dave

[@dephin2052]

hahaha nice one

[@melodazed7253]

a never ending huge thank you, professor dave!! your videos has been a great help for me until my college years today

[@amarynthia2990]

I have weak foundation in mathematics, and you just summarize all elementary lessons. hehe. thank you

[@Mr.ibraheem_HI]

You can communicate with me I can help you

[@theguythatdoesmath9863]

same here

[@joshyboi2q622]

How's life now

[@danielvickery1233]

You totally still get the correct result if you do it in regular PEMDAS order, it just takes more steps and thus reverse makes solving more intuitive. But in normal order you would divide all terms by -1, leaving you with -4 + b = -7. Then you would add 4 to both sides, leaving you with b = -3. But since you didn't cover terms yet, I guess most people would be lost with my explanation

[@GoumenPouSawKwè2008]

Great stuff to pass on to students. Thanks. And congrats on the new shirt!

[@squiredonald]

I have a learning disorder in mathematics, but this is really helping me, so far.

[@ljr6490]

🙂

[@conrad2939]

Discovered this channel for your debunking videos and found this while stufying for a college entrance exam. Through all of my years in school and the past months of studying, i never once came across the reverse PEMDAS thing. A whole bunch of stuff just fell into place. Thanks professor dave!

[@mbahauuakazondunge1725]

After i watch all this series i will claim my degree from KZbin

[@scratchingcatclaw]

How's it going? It's been 2+ years.

[@UniteAman4]

Now it's 3+ years​@@scratchingcatclaw

​@@UniteAman4 Now, it's 13+ days.

[@XouveZ]

its been 3 years

[@morbillionaire2785]

Hey tell us about your progress 😄

[@alyxkrieger6764]

All I need for my GED is Math. Thank You for making comprehendible lessons! I have Aphantasia and it was so hard learning in school.

[@ampersand2040]

GOOD LUCK! I WISH YOU THE BEST AND HOPEFULLY YOU'LL GET YOUR GED!! :DD

[@joshyboi2q622]

What does that mean alphantasia

[@ChildofAbba2]

Thank you professor Dave I understand it , didn’t get that in high school but you explained it very clearly❤

[@freedwolves582]

Oh. My. Gosh. I was Alr ahead of this type of math but when I learned new strategies like what you teach stuff gets wayyyy easier

[@einerplays731]

i learned many things here than my math teacher!!!

[@palivanoking]

Watching a week before I wright my finals because I literally had no hope 4 math but decided to believe in myself, I'm actually getting the hang of it 🎉

[@danag5610]

Now I know what to do with negative variables in an equation, thanks for this vid. :)

[@NeuroSwathi]

loved it! gave me nostalgia

[@x-unlockbr7237]

You're amazing, Dave! I'm from Brazil and love your videos. Sorry my bad english, I avoid to use a translator. Greetings from Brazil! :)

[@aleinsinmybackyard762]

Nice video

[@anthonystark6215]

Thank You, Professor!

[@luckygames8049]

you can also try this take the variables to the RHS and numbers to the LHS but change the signs so if a number in RHS say for example 2 is negative so (-2) you can take it to LHS make it positive and continue doing this hope this helps somebody :3

[@GladysRubala-ed4si]

This guy's a genius for making my dumb head understand math intuitively

[@supercoolninja]

1) x + 6 = 13 x = 13 - 6 = 7 7 + 6 = 13 2) x - 4 = 1 x − 4 + 4 = 4 + 1 x = 5 5 - 4 = 1 3) 5x = 70 70/5 = 14 5x14 =70 4) x/3 = 9 9*3 = 27 27/3 = 9

[@codexcodexcodex]

This is our lesson in our school today.

[@ladtm]

at 3:03 why did we subtract both sides when b was being subtracted shouldn't we do addiction?

[@rolfmannen9898]

well you have to get rid of 4 and to do that you have to subtract

[@asjsk8286]

thank u for your videos

[@kellycanicus421]

Why is 4-b=7 not 11? I added 4 to both sides then unpaused.😖 I don't understand why 4 was subtracted instead of added. Please help.

[@ProfessorDaveExplains]

because you have positive 4 on the left, you must subtract to get rid of it

[@kennedyrmenezes]

@@ProfessorDaveExplains 4 - ( - 3 ) = 7 --> 4 + 3 = 7. Right?

[@NickHope]

You're trying to solve b - 4 = 7 instead of 4 - b = 7. Big difference!

[@mohfares20]

Great job 👍

[@cgd295]

This vid is going to be 7 years in less than an hour

[@chourouk-gr9qg]

Tnx

[@JoelMcCary]

7 14 5 and 27

[@loveurself764]

This video is like one of those moments in class when everything just clicks.

[@dontstealmydiamondsv3156]

thanks

[@jinjiaaa]

Iam malaysian years 7 but when my teacher explaining i still cant understand when i saw this oh this is so easy hahah why i make so confuse

[@ophiuckus1635]

So, if i get through all the 165 courses I will be able to pass all math courses at first year of Geology at university?

[@depthmaths5399]

PEMDAS SIR, are we must follow the PEMDAS in algebra

[@Knowledge-Studio1]

Isn’t the inverse of subtraction, addition? Then why did he subtract 4 in the last equation rather than adding 4s? It would make b = 11

[@lanonate]

Because 4 is in the second place.

[@mikehess4494]

I prefer to use J as my 1st variable. It just makes more sense.

[@pobletekinze6537]

x+6=13 x=7 x-4=1 x=5 5x=70 x=14 x/3=9 x=27

[@LC-yv9ey]

X=7 x=5 X=14 x=27

[@earth_glows]

Love you 😚

[@ojayojay4015]

Got me all right! Ha !

I'm watching this in my calc class, don't tell anyone

[@Galaxy-ml1bx]

🤐👌

[@GirlSchool-hg7pw]

My mood got down and i feel demotivated by my sisters words but im going to use it toget the best grades im going for 20

[@shahabbaloch8338]

8 multply by 8 should be 64 why are they canceling?

[@kennedyrmenezes]

No, it's 8y/8, not y/64. If you divide 8y by 8 it's y.

[@cuzsie]

is that a vs dave and bambi reference

he changed the shirt haha

EVERYTHINGS working fine until this video came up now im cooked

[@maahir.sharma]

It literally took me 0.5 second to solve all of these equations.

[@ProfessorDaveExplains]

don't worry, it'll get tougher and tougher! stay tuned.

[@TiberiusStorm]

Nobody likes a showoff, Maahir!

[@mikehess4494]

It's about time.

[@shauravbhatt6718]

so now sir have changed there dress..

[@toorhideor8866]

aaaaaaaahaaaaaaaa!

[@Violetvisions86]

I still don't get it. I give up.

[@PrivateerJimmy]

dont make it hard for yourself. dont judge it (maths) although its a reasonable thing to do. thats one way to start

[@Violetvisions86]

I don't get it! I fall to see the logic.
