5T doesn't get anything done during @LeTour de France, so this is totally understandable. No apology necessary.
Apologies for slacking off last week. This is the cricket season. We are not being attacked by crickets ๐ฆ. Cricket is a game ๐, and a world cup is on. For us itโs bigger than football world cup ๐, formula one cup ๐๏ธ, super bowl cup ๐ and quidditch cup ๐งนcombined ๐๐๐๐๐โบ๏ธ

รvariste Galois was born today in 1811. Archfamous mathematician, partly for his peculiar death in a duel at the age of 20, but mostly for revolutionizing the study of #AbstractAlgebra with the pioneering both #GroupTheory and the theory named after him, #GaloisTheory #MathType
Five Triangles Junior (5ไธ่งๅฝขใใ) is getting to know the numbers to solve @1to9puzzle.
For anyone looking for a hook into this challenging @1to9puzzle, this is how we started. The 1 and 9 are the only unambiguous numbers.

This @1to9puzzle really could be called "Where's the nines?", in homage to the late Cliff Freeman, who wrote the now-classic question, "Where's the beef?"

There are similarities between this semicircle question posed to grade 6 students in Singapore and this ACT rectangle question posed to university-bound students in the US, except, perhaps, expectations.

75 years ago today the first atomic bomb was dropped over Hiroshima, instantly killing tens of thousands of the city's inhabitants.
Setsuko Thurlow, then 13, was one of the city's survivors. In 2017 she jointly accepted the #NobelPeacePrize in Oslo on behalf of @nuclearban.
A clever primary school problem.

Astounding: the sum of the areas of the squares are integral amounts. Does the pattern continue?
@BerrySlime3 ใใใใ
An intriguing problem for advanced primary school students, i.e., solve it without using Pythagoras' thm.
