@ECR_Maths @CasioMaths You will be lucky to get anything, I'm afraid. Have tried emails, contact forms, and Twitter – all met with complete radio silence. Works for me – I just stopped buying their products!

@CasioMaths I have tried to contact you via the contact form on your website, but have had no response.

Hi @CasioMaths, when I visit this link on my phone it gives a list of upcoming webinars (teacher and student) However, when I go to the same link on my laptop it says there are no upcoming webinars available. Is this a glitch? Thank you. education.casio.co.uk/webinars/

@hackloon @SteBel14 Also, I believe it was called Londinium back in those days...?

@SteBel14 All those places you were squatting don’t count, you know that? 😜

In order, where have you lived? Co. Durham Newcastle, New South Wales Back to Co. Durham Oxford Back to Co. Durham Oxford Back (can you guess?) to Co. Durham Brixton Balham Elephant Whitechapel Plaistow

@DrFrostMaths Also in OCR A Level Further Maths.

Coming soon: exponential distributions (in AQA A Level FM, WJEC FM and Singapore H2). I inserted the hyphen here to make sure students spot this cracking joke.

My current overall FPL rank is an unbelievable 185 (out of over 10 million accounts). But what is more unbelievable is the number 185 itself. It can be written as the sum of two squares in two ways! 185 = 4² + 13² = 8² + 11² But also...

Happy new year! Both of these lovely expressions equal 2024, and we're made in my last Y7 class of the year. #HappyNewYear

@paddymac_maths I think you mean brown and brown.

My pupils have asked for a Christmas fun lesson. So I'm writing in red and green.

@paddymac_maths This is my favourite idea for proving that. Looks like we're in the same place on the SoW...

1²+2²+3²+...+n² = n(n + 1)(2n + 1)/6

@sharpquillets Love this thread

I’ve been through a lot of airports recently. The range of quality is always surprising/depressing. Current rankings are: 1. Singapore - 11/10 as with everything else to do with the place it is impressive and efficient to the point of being unnerving.

@JohnRubinstein1 @Whitehughes I love me some underlining. I even double-underline my matrices (like a boss). I teach my students to do the same and tell them they get extra style-points for doing so.

@Whitehughes Who underlines anymore? 😅

@paddymac_maths @catrionateaches This was slightly confusing for that brief moment when I thought "rotato" was a portmanteau of "roast potato".

@catrionateaches I like to throw in the odd rotato-stretch into the mix...

More Underground Maths fun with year 13. Was quite fun getting them to predict what y = f(x/3 + 2) would look like. (Desmos trick for this sort of thing: I type the equation in with a repeated = sign so it won’t plot straight away) undergroundmathematics.org/combining-func…

@PaulGoldsmith73 I think it's more that they don't know what a free country is.

Siri, show me someone who doesn’t know what communism is.

@PaulGoldsmith73 @Jacob_Rees_Mogg I like this new, sassy Goldsmith.

@Jacob_Rees_Mogg MPs should not host news programmes but here we are.

@nickposford @MarcCanoBret @ThatGuyRobert1 @AlexTaylorNews @thetimes I mean, I didn't know this either, but it never hurts to Google.

My goodness ! Quite the letter in today's @thetimes (Important to read it right to the very end !) 👇

@DrFrostMaths live game down? Students just getting blank screen after log in?

@Ridermeister @paddymac_maths I also used the equating gradients method and it came out pretty easily. My final answer of 1/12 looks reasonable based on counting squares...

A tough integration problem - the difficulty lies in finding the value of k for y = x^2 + k to touch the square root mod graph... Find the exact value of the green area. Solution to follow. #integration #quartics

Hmm...I may get turned back at Heathrow for this, but it had to be said. Proud to join over 700 other composers in this infuriating protest.

@UKEnterprise Spoken like someone who has never reported anything to the proper authorities and seen exactly how prepared they are to handle traffic issues 😛

@Fellermaths Thank you for the post , Robin. All of our customer's are valid licensed drivers and expected to obey all of the laws of the road. When you see bad driving, please report it to the proper authorities in the area as they are best prepared to handle traffic issues. CM

@UKEnterprise Was just crossing the road on foot when the driver of one of your company's vans ploughed straight through a red light, almost took me out, then yelled at me out of his window as though it was my fault. 4:30pm on the corner of Madeley Road and the North Circular.
