This made sense to me. My private tutor has tried to go through this with me, but it hasn't really clicked until now
Amazing! Well I’m glad to hear this is working for you 😁🙏🏼🙏🏼
I could never understand this but now I do! This channel is really helping me this year in preparation for my exams so thank you!
So glad to hear that! Always nice to know the channel is useful 😁 are there any topics you are struggling with in particular?
Im struggling with graphs and shapes@@TheGCSEMathsTutor
Since I started using your youtube videos to study I haven't stopped getting 100% in my math exams and it's all thanks to u.
My man you are a legend, working through the AQA GCSE book and some parts don't make sense in the algebra and graph sections. Thank you so much for explaining things so simply 🙏
This 10 minute video helped me more than the teacher I've been listening to for 4 years
You explain this way better than my maths teacher thank you
So glad to hear I could help 😁🙏🏼
I never actually got how to do this topic until i watched your really helpful video! Thank you so much for helping me understand better! :D
I’m so glad to hear I could help! 😁🙏🏼
You make things so easy to understand. I wish you were my Maths teacher lol.
love this channel!! i've just started an accounting degree but i didn't do a level maths; i was feeling a bit lost in my first few business maths + stats classes but your videos have been really helpful to me for just going over the basics again and reminding myself of some of the maths topics i'd totally forgotten about since my GCSE days. thank you! ^_^
Thank you so much!!! These videos are really helping me and give me a better understanding of all the maths topics
TYSM! I've been stuck on this all-week. My teachery seriously doesn't know how to teach. Whenever you ask him a question, he responds: "No comment."
Oh dear that’s not good!! Well I’m so glad you have my channel here and it’s working for you! Keep being proactive 👏🏼 great that you are putting the work in!
I cannot thank you more i have a final test after tomorrow and I didn’t understand this lesson ❤

Omg ur so helpful
Thank you!!!!!!!!!!!!!!!!!!!
Thanks alot
Better than my maths teacher
Thank You
nice video man
Tomorrow I have a test on change the subject so thank you
Thanks
i got a question similar to 5:50, but i expanded the bracket and my my teacher marked it wrong...
What do you do if the letter you are trying to make the subject is under the divison bar? For example P=V/R (you need to make R the subject?
swap P and R so you get R=V/P
day before my maths gcse (well more like 10 hours before..
this has been so much help as i’ve always struggled with this topic. thanks so much honestly your channel has taught me so much over these months :)
Good luck mine is today too ^v^
we struggling out here😭
good luck to you too!! let’s hope for the best :)
yup😭 we will be okay though just keep going i guess :)
@@ainehoyle7558 good luck for your exam🫶🫶
Wow you teach better than my teachers
Thanks brother this helped a lot 🥰🥰😜😜😝😀😀
So glad to hear it helped! 😁🙏🏼
Thank you very much for your videos! They really help and ameliorate my knowledge on some difficult topics in maths. :>
My pleasure! So glad to hear the channel is helpful 😁🙏🏼
Thank you sir for helping me tomorrow I have my exams and I found your video to help me. Thank you it really helped me and I understood perfectly👌
Do you have any video on harder topics when the subject value is on both sides??
I understand the questions in the video, but I always seem to get the harder ones wrong when there is the subject value on both sides, so that would be helpful if he did have any more videos. ???
I have found it! ruclips.net/video/ugcR-khcTLQ/видео.html
is it wrong if i put 5p+ y, or the order doesnt matter
All ways feel better when i get questions right lol
but doesnt 5p change because there must be a change in times? 1:57
my question is on Make x the subject of y=x+3 divided by 5 shouldnt that equal 5y divided by 5 = x as you have to multiple by 5 in order to work out everything else which wouldve got 5y=5x+15 as you multiply everything that is in the brackets ????
I don't pay any attention in maths class in school, so videos like this really help. This helped me understand how to change the subject a lot better, so thanks!
thank you so much! I've been taking this topic for a whole week at school and i couldn't understand a thing, your explanation is very clear and helped me understand in 15minutes thank you so much once again!
Wait this is for GCSES bruu i am doing this in year seven lol but a very big thank you for teaching me how to do this👍
everything you do in yr 7 is for gcse this is foundation lol, this is yr 7 stuff
These are so helpful thanks
Is expanding a bracket as the final answer optional?
❤❤❤
Does it matter which way you put it round the letters with numbers ?
Emmanuel kalumba That entirely depends on the question but the short answer is yes! If you are referring to writing 3n or n3 then it absolutely matters, numbers always come first 😁🙏🏼
@@TheGCSEMathsTutor Hi does it have to be in order letter wise for an example s=w/a work out the subject w it would be SA?
@@merveilleekalakala4088 no. If it’s multiplication the order doesn’t matter, so you could write ‘AS’.
Think of 5x2 and 2x5; they both equal 10.
IVE BEEN STRUGGLING WITH THIS TOPIC FOR AGES THANK YOU SO MUCH HATVE THE BEST DAY EVERRRRRRRRRRR
Amazing news I really hope this has ended that struggle for you? 😁🤞🏽
@@TheGCSEMathsTutor it honestly did I’ve always struggled with making x the subject so thank you loads ❤️
Am not getting why u are adding 4:00
Sue Ali To reverse subtracting 8 from the one side you add 8 to both side leaving you with +8 on the other side 😁
@@TheGCSEMathsTutor thank u soooooo much, I have been watching ur videos and I can see myself improving. Can u make a video about polygons?
Sue Ali Great news! I’ll add polygons onto the list 😁
thank u so much i didnt get this at all since my teacher taught this in german bc of a silly language event. i think i already told u😂 anyway, ur my fav maths youtube account and my mum also likes watching with me tooo!😎
Haha I still can’t believe that 🤣 so glad you are enjoying the channel! Nice to hear it’s becoming a family event too 😁🙏🏼
Just got 66/80 in a mock exam, thanks a bunch.
Wow that’s amazing well done!!
@@GCSEALevelMaths Thanks sir
thats not xD sorry
You should be aiming for at least 75/80 but still well done i guess
Great videos, awesome channel! Face reveal at 100k subscribers?
Haha we shall see!! Thank you for the kind words 😁🙏🏼
bro what i finally understand these moon runes
a
in this answer y+8x4=x correct or this answer is wrong
Thankyou This channel is really helping me and could you pls tell me the answer
Don't forget that when rearranging a formula there shouldn't be any multiplication symbols! so 8x4 would be written as 12, but if you are multiplying the whole side by 4 then you would write that as 4(y+8) = x or 4y + 32 = x
Actually am not getting from 2:36
Thank you sooooooo much
Y = X/4 - 8 ... I don't understand how when you add 8 to both sides, you add it to right side and don't really do anything with it. And I get that it's changing the subject, not finding the value, but it goes from Y = X/4 - 8 to Y + 8 = X/4 and I understand how you get to that formula, but I don't understand how you +8 to 8 and then it just kind of gets forgotten for the rest of it.
Or is it because it's Negative 8 + 8 which is 0
Do we really need this maths in life?, I’m currently failing school and my mind can’t process maths in my head. I stare blankly at a question for minutes that slowly turn into hours trying to crack the code but I still fail to do so.
Gcse don't really matter. What truly matter is a levels or college.
@@sanykorodrigues5451 Not exactly, you should take your GCSEs seriously simply due to the fact that it's the foundation and proof of your worth ethic for universities to see (if you are planning on applying to them.)
Practice makes perfect, I didn't believe this statement when I started competitve programming but it certainly is the case here; GCSE maths is repetition and memorisation, start from the bottom and work your way up, scout the internet and join communities that can help you out on questions you are currently stuck on. In addition, you should also notice your weaknesses and strive to work on them. Linking back to the "strive to work" aspect of my "motivational message", you should spend multiple days really trying to grasp the topic at hand before making an assumption on whether you don't or do understand, I apply this knowledge in my own life and believe me it works.
@@sanykorodrigues5451 well yeah you need to do alright on your GCSEs so you can get into college
ikrr, there are some math concepts that are important but as you go higher math gets harder and more useless. im not gonna need this in the real world
