Let us start a #mathadvent! Day 1
🍃🌲
Tell me, on this first of December:
What is this digit that I remember?
When added to 6 or divided by 3
It changes, but it doesn't cease to be
A positive digit.
☃️🏂
On day 14 of the #mathadvent, more geometry!
Six-sided figure in my hand
It's one face of a solid gem
Lights out, I'm trying to understand
Gem's facets, ₐₜ least how many of them?
Si vous effectuez le produit de quatre nombres entiers consécutifs et que vous ajoutez 1, vous obtenez un carré parfait.
Exemple: 4 × 5 × 6 × 7 + 1 = 841 = 29²
Le nombre premier 1111114111144441142411444411114111111 (qui forme un palindrome) peut être disposé en étoile à 6 branches. Si vous concaténez le nombre de chiffres par ligne (1, 2, 7, 6, 5, 6, 7, 2, 1), vous obtenez aussi un nombre premier (qui est aussi un palindrome).
Day 25, 3D geometry and factoring, was a retelling of a beautiful problem from the 2003 Math Kangaroo contest, grade 7-8.
(It was another tough one, but you can try factors and find the answer with ease, or draw a picture!)

Day 25 (final day) of #mathadvent:
42 sugar cubes packed in one box,
Its bottom's length + width is 9 sugar-cube-sides.
Measured in sugar cubes, please work out the box's
sugar-cube height?

Day 15 of #mathadvent brings a tanka:
The largest digit.
Check if your number can be
divided by 𝖎𝖙:
add up the digits, again
ask if 𝖎𝖙's the sum's factor.

There’s loads of connections between maths and bellringing 🤓
Instead of tunes, ringers memorise sequences of changes - permutations where each bell can only swap with the one immediately before or after. In the video above, 11 bells move with the 12th always ringing last.
