Thank you! You are definitely the best math tutor on CZcams for igcses.
Wow, thank you 🙂! I hope to develop the channel and look at expanding the content through 2022 👍
@@GingerMathematician how about you take a look at edexcel one day!
im gonna miss watching u after i finish my exams
Always welcome back... teach others what you have learnt here?! 🤔
you are the most underrated CZcamsr, thanks a lot for your help!
Thank you please spread the word 🙂👍
Q9: No need to draw addition lines. ABCD is cyclic quad. The sum of the opposite is 180 so BAD = 115 (180-65 = 115)
This is true :-)
he is so concise and barely any seconds wasted
Like to keep it simple and to the point 😊😊
I've been having issues with this topic but this video helped me significantly. Thank you so much!
Great to hear Naiya 🙂 👍
your videos help me understand concepts much more clearly , thank you!
Great to hear 😊
I truly respect you, I am very weak at math and certainly a few other subjects such as chemistry… but with your help and a few other people, I have truly improved, thank you very much.
Happy to help! :-)
I love your video! It was very helpful, thank you for helping me along with others to understand math in a better way!
Great to hear :-)
thank you for your videos they are helping me revise for the exam tomorrow. grateful I found your channel:)
Best of luck Lenallistra for tomorrow 😊
Thank you so much for this video. IGCSE Maths will definitely be a breeze in a few weeks. Cant' wait!
No problemo 😊👍
I hope you start up with CBSE Maths if you can, I'm in IGCSE now but will be in CBSE too (Grade 11 and 12/ AS and A Level, and there no calculators are allowed, you could help us a lot as all IGCSE/AS/A levels have been uploaded by you already, you'll have a new challenge too!, and I guarantee you will see your channel growing faster than speed of light.)
Thanks for the suggestion! I'm always looking for ways to expand my knowledge base. Adding CBSE Maths content is a great idea, and I'll definitely consider it for future development.
The challenge of handling exams without calculators is interesting. It would require a different approach to problem-solving, which could be a valuable addition to my capabilities.
I can't guarantee a specific timeline, but I'll keep your request in mind as I explore new content areas.
thank you sir, the subs have been increasing and your videos make my day better. Thank you bruh man I really appreciate you
I appreciate that 🙂 Glad I can share my knowledge and experience to a wider audience!
Wow you are really amazing teacher.thanks for all of your support in my maths IGCSE exam which I will take next year.
No problem Mebratu keep working hard 👍
Thank you so much sir I learnt more than what I was taught in a year on the day before my paper
So long as you learn it that's what counts Enam 👍
Thank you so much! you have no idea on how much you helped me.🙏
No problemo 😊 😊
Thank you so much sir, you are really one of the best math tutors, and if possible please consider teaching igcse addmath too. I would really appreciate it.🙏
An All of iGCSE Add Maths is (slowly) in the works... 🙂

I believe in you! Go out there and show them what you know
Thank you Mr.Ginger u taught me how to spot the annoying ones helped me in school
Great to hear :-)
This video was really helpful! I really loved it and it's helped me clear my doubts on the topic of Circle Theorem. Also, I would like to ask how I may get the app you used as a calculator on my laptop.
I'm thrilled to hear that you found the video helpful and that it cleared up your doubts about Circle Theorems! As for getting the calculator app on your laptop, you can download the necessary software from the official websites of TI (Texas Instruments) or Casio. They usually provide software emulators for their calculators that you can use on your computer. Just visit their websites and look for the "Downloads" or "Software" section to find the appropriate emulator for your calculator model. Keep up the great learning and feel free to ask if you have any more questions! 😊📐🎉
can you please make a part 2 whenever you've got time?- this vid was really helpful!!!!
Hi Sara, this video seems very popular so more than happy to look at making a Part 2 🙂👍
If the question doesn't specify it,we don't have to put geometrical reasons right,also if we're finding angles instead of writing things like 180- the angle we can just forit on the diagrams right
Yes although a 1 mark question needs just the answer 👍
This is so helpful sir thank you 🙏🏾
You're welcome George 😊
This topic is mad and you made it a little easier. Thanks
Thank you Aisha 😊👍
Thank you, you are the best teacher, i really like ur teaching
Glad it's making sense Mithila 😊👍
Thank you so much for these videos , i cant imagine how i would perform without them , Your so clear and i undertsnad ..thank you thank you thank you
Try and keep it straightforward and to the point as possible 😊👍
thanks these videos are really helpful i really appreciate it
No worries I'll keep adding to the playlist 😊👍: czcams.com/play/PLYNwTLhq9xZbbYnEipbmqFWb4b-NpOkpd.html
Thanks, I’ve been stressing about something non school related and it has distracted me from studying well, I have 4 days left and I don’t know if I can finish what I have left on time but I’m just going to use your videos and some more practice
Just keep going is the most important advice at the moment Sissi 😊👍
BRO UR A LIFE SAVER THANK YOU SO MUCH
Pas de problem 😊
This video helped, I have an exam about this - Thanks!
Great to hear Peter - good luck for the exam 🙂🤞
Mr Gower you are absolutely fantastic ! Many thanks 🙏
How's the revision going Jade? 👍
@@GingerMathematician so far so good sir 🙏
i thought cosine rule for angle was b squared + c squared - a squared divided by 2bc
Can use different versions 👍
Thank you. Thank you. Thank you! You are a lifesaver.
No problem Nicole 😊 - when are your iGCSE exams?
I'm writing maths on the 17th. Hoping for the best!
Thanks a lot for your wonderful and easy explain and it really helps
Glad to hear that! :-)
I always thought you were british, never thought of you being german. Anyways, it feels like you're way more passionate to teach us than our teachers. Love you energy and tricks. Thanks for the vid :)
I am British but I have lived in Germany for almost a decade 😊 - fast eingedeutscht 😉
So helpful ❤❤❤🎉🎉🎉thank you so much ❤❤❤❤wish you were my maths teacher 😊😊😊😊😊😊
Thank you Keshalia 😊
Thank you so much for this video.
Hope Circle Theorems are now a little easier 😊👍
Thank You so much for this Video !!!
No problem Mahimann 😊👍
This video was really helpful, highly appreciate it. Would it be possible for you make a part 2?
Had a few requests for this Mariyam, will look into it 👍
@@GingerMathematician appreciated
Sir i do have a question, In a isoceles triangle wouldn't the 2nd angle be 72 degrees in Q12, since 2 sides and angles are the same, if not sir can u clear the conseption?
thanks for the help!
No problem 🙂👍 Please share with anyone with iGCSE Maths exams coming up 👍
Hi sir, im in just love with your videos, just need a few suggestions, im personally having problems in probability, and in the questions where they either ask to find out the number of angles or the degree of each angles, basically the questions which use (n-2)x180 as a formula.
Another question is that sir the exams are soon, and im confused whether is i should do specimen papers as well, whats your take on this?
All of iGCSE Probability you can find here 🙂: czcams.com/video/9WiCRHYqLkc/video.html
As for Specimen Papers, they are usually a little harder than past papers but excellent practice for the hard parts of the course 🙂👍
thank you so much please touch on exponential equations
Interesting topic Kyla, thank you for the suggestion 🙂👍
bro u for real saved my life i love you the best math teacher ill make a edit of you after my exams
Lol looking forward to it 😅
wow, thank you so much, this was extremely helpful!!
Great to hear 😊👍
The best one for IGCSE maths
Thank you 😊
im so grateful for ur chanel writing in october
No problem Lisa, have you been through the All of iGCSE Playlist?
angle B in 42:19 is 90° since angle facing the diameter is 90°!
Lol I think I mention that later in the video... but shows you can take one of many routes to the correct answers 😂
SO HELPFUL THANKS❤
No problemo 😊👍
Thanks a lot for this video sir.
No problem Shiv, some interesting similarity questions embedded as well 👍
@@GingerMathematician 👍
I think you r extremely underrated bro, u put so much work in to ur videos.
Thank you Adwaid for the appreciation 😊👍
@3:04. Not a cyclic quad there already? Isn't ABCD a cyc quad? They are all points on the circle. (4:53 - Are all vertices on the circumference - Yes, it's given). Or is there some rule that the quad has to be in opposite parts of the diameter? Thanks
You can use that cyclic quad straight away Richard yes 🙂 👍
Thank you sir 🙏
No problem 😊👍 Vectors coming out soon too 👍
Sir, for the 7th question at 38:04, to find y I made a trapezium and used cyclic quad by applying the formula 180-110. Is that correct too?
Yep Agam that also works 😊
Hey Ginger Mathematician I cannot find any video regarding tips to solve algebric word problems 0580 which I loose the marks at the mostt and secondly finding volume questions specifically for example 0580 oct nov 2015 Q3 thanks
Hi there took a quick look and doesn't seem there is much out there for iGCSE Algebraic Word Problems; I will take a look! 👍
youre the best ginger ever
😅 Thanks Sama
At 37:28 why can we use y since it is at the circumference and make it 70
But is y acute or obtuse?
I LOVEEEE UR VIDEOS TUANK U FOR HELPING ME OUT
No problemo :-)
Thank you Sir this has helped me a lot my Maths Paper 4 is tomorrow
@@malaikadar4365 I will 🙏
Best of luck Malaika and Aaran 👍
Do you have a video on explaining the rules first? As I don't know any of them
Not yet...
thank u sm omg paper 4 is on monday
Not long!
at 22:00 if we do cos inverse (4.6 squared - 2 squared - 5 squared/ 2 times 2 times 5) thats fine as well right
It is!
Mr. Sam, do you have a video/ do you have any ideas of making a video about transformation matrices? I’ve seen a lot of transformation matrices questions and I never get full marks on them - my search on yt and google has always been inconclusive so if you can help me then it will mean a lot thank you.❤
No transformation matrices on iGCSE Cambridge 😊👍
Same here.
can you plzzz do a video on cordinate geometry , would really apreciate it ( great video btw really nc teaching skills u have thank u )
That and Percentage Calculations are still to be added 😊👍
Sir, at the time stamp around 20:30 You labelled Cos A as AXD is it like absolutely necessary? My teacher actually cut my marks because I didnt write what angle I was finding (I labelled angles A,B,C and lines a b c on the diagram) for example the angle that was a for me in the exam was labelled M but I just kept it as A.
Hi Manu, no is the quick answer as the exam paper will have AXB already written. But certainly for good mathematical written communication you should write it 🙂👍
for q 12 c wouldnt the answer be 72 as dec triangle will be isocles due to the tangents to circle theorem ? thank u for the vid btw :)
Do you have a timestamp Kaps? :-)
great video
Thanks Arman 👍
Hi! i just wanted to ask why is it at 6:25 , you just sorta used the cyclic quad approach instead of just adding 3x and 6x, considering the fact that it is a triangle after all and it should add up to 180 degrees
Can also do that too :-)
for the first question (b) why cant u use the rule angle at centre is twice the angle at circumference??
You can as well 👍
Hi i would like to ask which line do
you mean we use angles on straightline on 10:43
Using angles in a triangle add up to 180 degrees here :-)
I want to punch the air everytime I see congested triangles in a circle like some toddler scribbled on the circle
Haha love the enthusiasm 😅
Please upload the prediction for IGCSE mathematics 0580 paper 2 and paper 4
Your videos are best for IGCSE
Already done 😉👍:

Thanks for the vids! I have my paper 2 in a few hours lol
And how did it go?
@@GingerMathematician I did really well! I messed up one question though, i guess i have to focus on preparing for paper 4 now
Love your video brother
Appreciated 👍
Hello gingerr sir thank you✨
No problem Faiza 👍
Soon, I am going to write history, my past. Those board exams will be my past and they will be a part of my history.
Just take them one step at a time 😊👍
Sounds like a start for some thrilling adventure!!!
@@mantosh56 4 more exams to go out of 21.
thank you 🥰
No problem Yosan 🙂👍
Hi there sir I have a q, there's not going to be matrix, constructing triangles and map scales right? Thanks
Yes, correct 🙂👍 How are you feeling about the exams?
@@GingerMathematician I feel pretty good, I have practiced all paper 2 from 2021 and some from 2019 and 2018, (and did the feb 2022 22, 42 ones), I feel the feb 22 and 42 2022 were much easier then all of 2021 papers, I need some more prac on paper 4 though. Are bearings still in the syllabus, if yes then I need to brush that up too. Thanks!
thank you
No worries 😊👍
Hey Sir, great video; but is there any specific reason why you didn't take the whole triangle ABC at about 35:00?
The whole quadrilateral thing is a bit confusing.
No reason, taking the triangle and using that is a great alternative method 🙂
@@GingerMathematician Thanks Sir!
thankyou so much.😇😇😇😇😇
No problem 👍
wow amazing video very helpful but do you have a tutorial video on how to calculate surface area of 3D shapes
In my Mensuration video? 🤔 czcams.com/video/ojUG8BYEB9g/video.html
thanks alot
No problem Aarush 😊👍
Have paper 2 and 4 in 7 days any tips?. Have done about 60 pastpapers. However scoring 75%. Aiming for 90%
The key thing at this point is keep up with the past papers, especially the most recent ones from 2021 and 2022. Otherwise you sound set to go 🙂👍
THANK YOU!!! YOU ARE THE BEST!!! IM GONNA PASS MY TEST BECAUSE OF YOU TOMMOROW, THANK YOU ONCE GAIAN!!!
Best of luck for tomorrow 🙂

Hi im just wondering at 9:48 why u dont consider seeing the entire triangle as isoceles triangle and just do 180 - (18+18)
Can also do that too Lou 😊
7:23 can we do 6x+3x+x=180. So 10x=180. So, x=18?
Exactly Shiv 👍
@@GingerMathematician 👍
Thank you Ed Sheeran now I understand everything. Tomorrow I have my exam wish me luck
Go smash that Paper 4 😊👍
