Mathematics

[Jian]

Hi, I am new to this. Does anyone love maths here?

[Me, me! I do!! Harry]

[Jian]

Haha Harry

[Jian]

e^ipi + 1 = 0 is my favourite. Do you agree harry?

[It is very beautiful! Harry]

Numbers are surprisingly wonderful.
I mean who would have thought that the decimal part
of the 18 reciprocals of 19 would give…

All 18 reciprocals of 19…
1/19
2/19
3/19
4/19
5/19
6/19
7/19
8/19
9/19
10/19
11/19
12/19
13/19
14/19
15/19
16/19
17/19
18/19

Take decimal part, stopping at repeat
(which happens to be the 18th decimal)

Take decimal portion only giving an 18 x 18
Magic Square – where each row, each column
and the two long diagonals add up to 81

The wonder of it!!

First year university maths student here, I definitely love maths

[Jian]

oh my goodness i never noticed that thanks for enlightening me!

[Jian]

anything else? I really like the proof of fermats last theorem although it is very complex i still understand what is going on even though im in year 8

[Are you sure you don’t mean the proof of Fermat’s little theorem? I only know a handful of people who understand what is going on with Andrew Wiles’ and Richard Taylor’s proof of Fermat’s Last Theorem! Harry]

[Jian]

I meant that I know the proof by contradiction, not all of it

[Cool! Harry]

[Jian]

And i do know fermats little theorem

[Also cool! Harry]

[Feefen]

Wow TLW, that’s some amazing stuff! Thanks for sharing. Also a math enthusiast here!

[Jian]

wow nice to meet you

[Jian]

it is so beautiful it keeps me awake at night. Same?, harry?

Fellow maths lover here. Hopefully, I’ve interpreted 6B correctly, so Harry I was wondering if you could recommend any resources on number theory. If I am completely wrong about the message then I would still like to know what works on number theory you find interesting.

[Possibly nt write on the trail of 7B hints yet, but I can thoroughly recommend learning number theory anyway! There are many great resources on the web. Perhaps people would like to nominate their favourites before I weigh in? Harry]

[Jian]

i couldnt do 5B lol. I do like number theory though, very interesting

[18goyaan]

Anyone done the BMO1? I’m in Y9 and I loved (and still do love) Fermat’s Little Theorem and Fermat’s Last Theroem when I was in Y6
