I've never been one to pass math ever but I recently got back my GCE N'Level Examination results and I thought I was going to fail since I only started studying last minute but to my shock I passed. I didn't pass with good grades but I still managed to pass and that's all I'm happy for. This channel really helped me understand math easily compared to when I studied in school. Thank you very much!
Man cognitive explained it so well man I’m in year 8 about to go into year 9 and I learnt it in like the first few minutes. Ultimate combo cognito+freesciencelessons 🎉
I’ve always struggled with math and been close to failing in school but now I understand and have raised my math grade!!!
This channel saves me every time I got a test 😂 my maths teacher actually explains it to different and barely anyone understands what she is saying half the time so thank you! 😂

Honestly there are a lot of different revision channels with there respective learning patterns but the way cognito shows and explains the work for the specific video is great u can pause at any time to write notes tips and personal options down let alone the fact that cognito explains everything perfectly so that u can understand what u are trying to work out step by step is jsut perfect for all revisers well educated of not it’s perfect for everyone personally this channel is helping me a lot and by the looks of it this is 2 years old and still affective! So thank u I saw this in my maths book and thought I was going to suffer but not any more ✌🏽
Came here for the simultaneous equations step by step. Such a straight forward and easy-to-follow video. Thank you :)

I suggested your channel to all of my classmates and they found it very helpful I must say tho, the website is a piece of work! it is very helpful tho can you add 2021 and 2020 papers too? Thanks have a good day!
thank you so much for the great explanation
Hi, I hope you are having a great day. I was just wondering if you could possibly make videos related to history in the future, because you guys make such great videos which are easy to understand and filled with information, and a lot of people would probably like history videos. Also, when can we be expecting the math part on the website?
@jajalulujaju

I think for history you just have to memorise like know the timings and what’s going on that time and also remember the answer structures.
Thank you so much may god bless you your the GOAT 🙏🐐

4:57 idk of im just being stupid but i dont understand how het got that from -2x from both sides.

bc -2x from the right side just takes it away from that side completely and adds -2x to the opposite side
Will you be updating your website? On the website it says some of the videos are "coming soon" but are already posted on the channel
Omg, thank you. You helped me pass some of my tests this week thanks ❤
I'm doing this work at home when I'm in grade 6 because our school doesnt teach us math that is complicated enough. I didn't realise it would be GCSE, but I think I will follow this channel and continue with stuff like this ❤️

You made it SO easy, i have paper 2 maths tomorrow (or actually today, at 8:00am, its 12:00 am rn) Edit: 1 simultaneous equation came and i fumbled the ball 😭😭😭😭. Im so bad at math and good at everything else WHYYYY
i kept denying that i was right cause i got a non integer awnser but then i kept watching and realized im too tired to revise and went to sleep
Just a quick question, how does y=1 at the start? I understood everything up to that point, 2y=2 so how would y=1 x

Because if 2y = 2 then a singular y (1) = 1y
Thankyou so much ❤ my child is in Gcse board he was having problem to understand science and maths of gcse board but it is easier for him to learn now thankyou😊
In the 2nd equation, at '6:21' the solving is wrong: Y - 6Y is not 7Y, it is (-5Y)

how is y + -6y = 7?
@fraudulentminke_
Ай бұрын
it's subtracting, so what we're actually doing is y - -6y but since there are two subtract symbols, it turns into addition, so in the end you're doing y + 6y to get 7y I'm not the best at explaining and I'm assuming you were revising for GCSEs which have already passed, but oh well 😅
Cognito i think you should make make a video on the other method used to solve simultaneous which is substitution
thank you SO much for this video, what a livesaver
I love this video cognito thank you
Cool
Yeah im finished
Awesome!
thank you so much for this really clearly and effectively explained.
Hi! I absolutely love your videos! Question - is there a video for solving simultaneous equations using substitution? One of your videos said that there's a video for that but you've got 2 graph videos linked to simultaneous equations and one video on elimination. Anyways, you don't realise how much this is helping us!
can u make a video on simultaneous inequalities
Hello Cognito This video is not on the website by the way.
Can you please please start doing Alevel content.I loved cognito for gcse it got me 7s and above in maths and science and nothing compares with your videos.

how do you know whether to subtract or minus on the first step ?
This helped me only 2 minutes was left for the examination
thank u sooo much it helped alot
I am in year 9 haven’t been taught in school and I leant it in the first 2 min😂
thanks im just a kindergarden and now i learnt hight levels math
i just have to say that singapore’s method is way harder than this as they are more steps than this one.
Thanks
6:24 what if our answer cant be divided
@hadiqaa7336
2 ай бұрын
i think you mean what if the divided answer is a negative/decimal, which is fine. for example 5y = 66 we HAVE to find Y. So you HAVE to divide even if it’s not divisible by 5. so 5y = 66 = 66 divided by 5 = 13.2 Y = 13.2. this is a random example btw. sorry if u dont get it but yeah its ok if u have negatives or decimals, good luck!
Hi could you please make a video about substitute method thank you❤❤
