Who leaves a 2x2x2 like that???

I still gave this video a like, but…

Idk…I'm gonna be checking that,

my OCD just got maxed out >D

"If you ignore the 0 all the number keys for a

ParkerSquare" – Matt Parker 0:14Since you like shapes, who doesn't, I picked up a "Euclidean Cube" and have been baffled with it's many hidden faces even though it's a "fairly simple" joining of a few squashed looking Tetrahedron's linked together by the edges (with some magnets as well). I'd love to see if there are any interesting properties about it that a aren't as obvious to those of us that haven't studied math as much. You can even put a bunch of them together to make even crazier looking objects and at the moment find it as my most interesting cube shaped desk toy. Also if you know of any other cube shaped desk toys I'm all ears, I have a collection growing at this point.

Mind.blown!

2:43 I prefer the term "Parker Rectangle"

22 seconds in and I can already see the parker square. You're not fooling me buster.

In València (Spain) we have Som Energia

I knew you were a clockwise kinda guy Matt.

🤯

also works for "diamond" patterns (eg 4862), "hexagon" patterns (eg 148962), and "6-digit triangle" patterns (eg 159632) !!

I did my own research. Support nuclear power for green electricity 🙂

The center will hold as long as matt parker is protected at all costs.

Found a pattern you might enjoy:

1254/11 = 114

4521/11 = 411

8965/11 = 815

5698/11 = 518

7854/11 = 714

4587/11 = 417

ect.. ect..

I need to stop procrastinating my exams now.

The pattern actually works with any parallelogram you can draw with the buttons! Even if you use 0, although you have to pretend it's underneath the 3 (where it should be)

It doesn't even need to be a rectangle. You just need to make a loop. E.g. 793254

And it can even have loops: 12541397

Works on the diagonals with 4, 8, 6 and 2 combinations too.

Haha!! I did the same 30 years ago 🙂

I would like to remind you that parallelogram is a very broad term, and thus caution against saying "any parallelagram" would work on your admittedly ridiculous calculator face. "241513" is not a multiple of 11, despite being the concatenation of the four corners a parallelagram in counter-clockwise order (2, 4, 15, and 13), because squares are technically paralellagrams.

there is an interesting pattern with the quotients. For example, take the number 7,843. the leftmost digit of the quotient is equal to the leftmost digit of 7,843. the next digit is equal to the third digit of 7,843 minus the last digit. and the last digit is equal to the last digit, so we arrive at the number 713.

I thought you were going to do the 43770 trick

you did your own rendition of the meme?

NiCE

It also means there are no "rectangle" prime…. I let a little tear out

i have 200% renewable electricity thankyou 😉

It also works for the square of height/length 0, say 5665. Call them degenerate solutions? I wonder how you would go about this in a hypercube situation. I guess you would need an orientation – maybe the orientation of two simplicies of the same dimension as the cube glued together? Or I guess the simplicies could be any dimension, really. I would investigate this but, you know, exams 🙁
