Yes, me. Not every week, but most weeks, I write a mini-thread about Maths - #MathsMonday - because I've seen enough #disinformation #misinformation on #Wikipedia to know the only true way to spread the word is to have a place where no-one else can back out your literal textbook [β¦]

Over time I have saved many screenshots of #AI #aiSlop stuffing up #Mathematics big time, and on occasion I've had cause to reshare them, and at times I have cursed that I can only attach 4 pics per post. Then I realised, what am I worried about - just post them [β¦]

This #MathsMonday I'm expanding on #scalars in #Mathematics. Previously we discussed that integers in #Maths are discrete, and used for counting things. In #Math we also have the Real Numbers, which is a bit of a misnomer since we don't usually use them for [β¦]

This #MathsMonday Why there isn't an #infinite amount of #numbers between 0 and 1 on the #number-line AKA The number-line isn't a TARDIS!
Firstly, one thing to point out is that people often conflate numbers with #numerals. This is important [β¦]

Yep, and I'm a Maths teacher. The chance that ALL are false accusations (at 90% each) is 0.9^26, so the chance that 1 or more is true is 1-0.9^26. For 10% it's still 1-0.1^26

This week I want to come back to the "proof" that 0.(9)=1, which I debunked at https://dotnet.social/@SmartmanApps/112711027003047449 At the time, I said there was insufficient information, because it was unclear [β¦]

Captain Jack Sparrow meme - "The difference between 0.(9) and 1 is infinitesimally small", "But there is a difference!"

#MathsMonday #Mathematics #Maths #Math
So we've seen that 0.(3) is merely a decimal APPROXIMATION of 1/3, due to the limitations of using Base 10. It's also true, for the same reason, that 1 is merely an integer APPROXIMATION of 0.(9), since 9 is infinitely [β¦]

I'm pro-facts, and anti-AI because I'm also a #Mathematics #teacher and #AI is horribly bad at doing Maths (can't reason). Students (or anyone at all) should NOT be using AI to learn Maths (or do their homework)! I just posted today about how AI is bad at tutoring. I run 2 (intermittent) [β¦]
Cartoon of 2 people saying "In other words 0.999... is not 'almost exactly' or 'very, very nearly but not quite' 1 - rather 0.999... and 1 represent exactly the same number. It's useless... It's all useless... This number is equal to 1"

I'm coming back to the topic of 0.(9) (i.e. 9 infinitely recurring) not being equal to 1, even though I already discussed the "proof" (which isn't a proof) at https://dotnet.social/@SmartmanApps/112711027003047449 as I've found there are [β¦]

This week I'm going to look at the #Mathematics 5x3 issue which blew up a few years ago, where a student answered 5+5+5 and the #Math #teacher marked it wrong and said it was 3+3+3+3+3, because her reading of it was "5 lots of 3".
