wouldn't starting with 4 and 6 as the two consecutive even number be more correct for the very last question? my answer was 8(n^2+3n+2)+4

I swear everytime i watch one of these videos, my understanding of maths always increases by at least 20%

I’ve been trying to learn proofs for weeks for my maths mock tomorrow, you’ve helped so much, thank you!

[@TheGCSEMathsTutor]

So glad to hear that it helped! Good luck with your mock exams 😁🙏🏼

[@aaryanramani1699]

Brilliant explanation. Watching this in the summer holidays to revise Grade 9 Questions always helps...Perhaps that's the reason I am subscribed to this channel

When I have seen this questions in past papers, I have had no idea how to answer them and I thought they would be really complicated.. But this is pretty easy. Thanks

cheers boss man, all these videos are really good and i’ve been binge watching them all for my test tomorrrow. thanks man

[@heidiim4825]

omg thank you so much for this video. Algebraic proof has been one of the topics in maths that i have always hated because i never understood how to do it but this video actually made me realise how simple it is (like most things in gcse maths) once you get the hang of it. THANK YOU!! Good luck to anyone else doing exams this year!

[@Ramyaishan23]

In a week time I have learnt a lot of higher maths from your videos and its really very helpful for a person like me working as a TA in secondary school ! Do lot more videos sir !

[@idkwhatthisis7319]

Thank you for your videos I used them to revise for my mock exams and my exam went very good!

[@DavIDOfficialBeats]

watching this at 11pm before my non calculator maths exam tomorrow. this helped a lot - way better explanation than my teacher's

[@laeyak8504]

just got an add talking about how its hard to find helpful maths videos on youtube, and that i should use their app. im literally about to watch the exact thing i need, thankyou very much

For 17:11 if you got the anwser 3(n+1) would that still be correct?

Do i need to write an explanation for each question? Or are the numbers alone fine

Numbers fine

[@Zeemish]

@@Fpl_Thomas thanks

[@hh-ms3ub]

i would always suggest writing a small statement, I remember when I lost a mark for not writing one.

At 17:25 could you have used 2n+2 and 2n+4 as it does say ANY consecutive even numbers?

[@lolllhello7718]

Thank you

[@Just_Tey]

For even numbers you used 2n and 2n+2. Can I use 2n+2 and 2n+4. Does it matter?

[@turbiyo4026]

Hey great video do you know what specific grade the first few questions are?

[@TheGCSEMathsTutor]

Turbiyo They are all grades 7-9 but it is near impossible to allocate a grade to every single question here, but as a rough estimate I would say 7 😁🙏🏼

[@turbiyo4026]

The GCSE Maths Tutor ok thank you

[@hannahwood2543]

Thank you so much !! You have made such a complicated topic so simple and sort of fun lol . This video is titled grade 7-9 math . What essentially does this mean ?

[@danid251]

Basically knowing these topics and being able to understand them puts you in the range of getting a 7 to a 9, which is equivalent to a 7 being an A and a 9 being an A*. I hope this makes sense !

Can you put (2n-1) and (2n+1) at 13:35 or does it have to be (2n+3)?

Aaryan Ramani Absolutely you can! 😁👍🏼👍🏼

[@aaryanramani1699]

@@TheGCSEMathsTutor Would doing so, make the question harder or easier?

[@TheGCSEMathsTutor]

Aaryan Ramani That entirely depends on your comfortability working with negatives, I would say it’s the same difficulty but some students may find it more difficult as you have the be more aware of using negative numbers. Although any student accessing algebraic proof I would argue should be pretty confident with their negative numbers! 😁👍🏼

6:38, n^2+n+n+1 would factorise to, n^2+n+n+1 = n(n+1)n+1? meaning its n(n+1)(n+1) ?

Hi, when factorising, numbers can only be divided by whole numbers. Can't factories using a fraction or decimal.

[@ksfjoisu8r094]

At the time of watching this video the likes are at 969, I think this is a really unique number so i will leave it like that Btw, this video was great, You could improve you're video's by splitting the video into 2 sections 1 for teaching what to do the other practice questions so you're video doesn't look to long that's one of the reasons why i sometimes don't watch your video because its sometimes too long

how do u prove its never a multiple?

[@ahmedawan8505]

Sir, on 13:10 i got 6(n+2) is that correct as well

No because that means it would be 6 times 2 which is 12 because everything in the bracket gets timed by 6
