📸 A small photo report from the Mathematical Festival, which took place on February 9 at the Economic Faculty of Lomonosov Moscow State University in Moscow. Our station 'Pythagorea game' was very popular. Three tables were not enough and children enthusiastically solved problems standing all around and even on the floor. Their parents and organizers were also curious and then could not stop solving our #puzzles. Thanks for the great festival!🙏 #math #mathgame #mathfestival #Pythagorea #Euclidea #conference #mathematics #geometry

#didyouknow that? Or 6 interesting facts about 2020. ⠀ 💥 2020 is the 22nd natural number for which the sum of the digits is equal to the number of the digits (in other words, the #arithmetic mean of digits equals 1). ⠀ 💥 "Two Thousand Twenty" - all words begin with the same letter in English. ⠀ 💥 All the digits of 2020 are even. In its square and cube all digits are even too. On the contrary, in 2020th prime number p(2020) = 17579 all digits are odd. ⠀ 💥 The 2020th decimal digits of constants π, e and φ are the same. By the way, this property is not so rare. The minimum such number is 12, the predecessor of 2020 is 1905, the next will be 2060. 3,141592653589 ... 12694683 ... 2,718281828459 ... 82922443 ... 1,618033988749 ... 43062623 ... ⠀ 💥 According to a hypothesis of Wacław Sierpiński, 2020 is not representable in the form x^3 + y^3 + 2*z^3 with integers x, y, z. ⠀ 💥 2020 is self-descriptive. A self-descriptive number is b digits long, indexed by 0 ... b-1 and for all n, the n-th digit equals the number of n's in the number. In the number 2020 there are 2 zeros, 0 ones, 2 twos, and 0 threes.
