"As we say goodbye to 2025, let's delight in its numerical charms one final time. The year was unique this century as being a square number. 442 = 1936 452 = 2025 462 = 2116 And since 45 = 20 + 25, we marvelled at the dazzling pattern: (20 + 25)2 = 2025 Good times."
"To the puzzle: Auld lang signs Here is an expression equal to 26 that uses six 1s: (1+1)(1+1+11) Find expressions equal to 26 using: Five 9s Six 8s. Six 7s. Six 6s. Four 5s. Six 4s. Four 3s. Four 2s. a partridge in a pear tree. (Only joking)"
"You are only allowed the four basic operations, +, , x, , brackets, exponentiation and concatenation. (Exponentiation is when you make a digit the exponent, such as 11. Concatenation is when you join digits together, such as taking two 1s and making 11.)"
2025 is highlighted as a rare square year, with 42^2 = 1936, 45^2 = 2025, and 46^2 = 2116. The identity 45 = 20 + 25 leads to (20 + 25)^2 = 2025. 2026 is noted for its digits 6 and 7. A puzzle requests expressions equal to 26 using specific counts of identical digits: five 9s; six 8s; six 7s; six 6s; four 5s; six 4s; four 3s; four 2s. An example using six 1s is (1+1)(1+1+11) = 26. Allowed operations include addition, subtraction, multiplication, division, brackets, exponentiation, and concatenation. Readers should avoid spoilers and share favourite aspects of 26.
