Maths Help with Mr Orys
Добавлен 7 июл 2014
A collection of videos to help you with Maths! Some of the videos are on calculator technique and some are on mathematical methods. If there is something you would specifically like a video on, just send me a message and I'll do my best to help out.
Two lessons I think everyone needs to learn....
Something a little different for my channel today. I was asked to provide something for a school assembly that I would like everyone to learn, and so here is my contribution. I figured that even though it is not Maths, and different to the usual content of my channel, it may be of interest to some other people out there, so I am making this accessible to everyone, in the hopes that it finds a receptive audience. Take care, and stay safe.

感谢您的分享! 只是我有一个简单的题外话问题: 我的OKX钱包里有USDT,并且我有恢复短语. [pride]-[pole]-[obtain]-[together]-[second]-[when]-[future]-[mask]-[review]-[nature]-[potato]-[bulb]. 将它们转移到Binance的最佳方法是什么?
Is there an exam mode for this calculator, the fx-9860GII is not allowed in my A level maths exam, and my teacher says I can only use it , if I can put into an exam mode, where I can't do things like integration using the calculator
Hi , the method is fine but at the end when you are selecting the higher value you was very fast I could not under stand what I am beating and what I am having and what conclusion I have reached please do add another graph to see what is happening at the end ! Too confusing
How from A to E is 20 ? On top row ,??? Should not be 21 ???
Ik am late but does any1 know when i reset my calc i lost my periodic table and more stuff any1 know why and how i can get it back?
Hello, can you do a video on how to find combinations on a Catiga cs-121? Thank you!
Brilliant video, thanks :)
How on earth did boomers have trouble exploring modern computers is my question.
Hi can anyone knows how to change the button X10x button from E format as it shows in the video after the 6.45 minutes played to the x10x format. My one does the same E letter instead off x10x. Thanks
Can you make a video with a representation of percentage calculation with casio fx 9860GII. Thank you
Nahom disliked your video :(
You’re my hero
想不到, CG50已經有超過10年的存在。
export and import with the connection is much more important!
🤣🤣so CG50 is also the same input 'culture' of degree-minute-second style followed!! THX for your 9 years ago video so I could try my CG50's degree-minute-second function!!
It's not working on mine
I love the design of the CG 20 especially the button spacing and colours. It looks very sturdy and gives off vibe of old blackberry smartphone.
I was so stressed out i wasnt going go be able to do anova for my final tmw THANK YOU SO MUCH<33 MUCH LOVE
How would you calculate the errors corresponding to the coefficients?
I have been calculating this by hand hundreds of times. You, sir, are a gift.
Very helpful, awesome,... (Amirah S.J. I hope you reach this video)
Instead of 58 there should be 2 PS. Thank you for all those videos!

Exelente video funciona perfecto para la calculadora Casio fx-9750giii
Man saved my exam
these are so helpful thank you so much
Is it not better to cross out the columns, for instances such as when you have a directed graph?
the best one, searched so many places, this one is the best
THANK YOU 😭😭
I was not sure why the exam questions always ask for lower bound and upper bound for TSP problem; thanks for clarifying!
Me for example I circle the pivots I thought towards the end everything must pivoted labels as pivot ( in my case everything must circled towards the end ) the course I do is edexcel A level further math option decision 1
Can you please answer me ? I tried to graph 45 times square root of x times cos of an angel of 0.06x squred and it gives me an empty graph , what can i do please?
How do you get the engineering value on this calculator? other Casio calculators have an (ENG) button can't see it on this model.
You're an absolute legend for this.
you literally saved my life thank u so much from 2024😭😭😭😭
Inter key no working
Unknowing, did this video become the last & goodbye video?
thaaaaaaaaaanks
Amazing astounding beautiful
Why did we not write s2 in basic variables?
What if the BIN has a limited number of slots additionally to limit in full size?
Thank you so much for including all the Row Operations in the tableaus. Nearly every other video thinks the row operations are "obvious" or "trivial" so doesn't bother including them. As a beginner it makes it a nightmare to follow along. It's conceptually easier to consider this as a Linear Algebra problem than an approximation problem.
Yes inoino
Thank you for the advice It made me feel better
Thank you
Math!
this helped loads thank you
Thank you so much, my online teacher was telling me to use DMS but I couldn't even navigate this calculator properly as I hadn't been taught everything about it. 8 years later and still changing lives. Thank you.
This video is so useful. Thank you so much. Also loved the music at the end
I like 'em big
