As 2025 draws to a close, it’s worth noting its mathematical quirk: it was a perfect square (45² = 2025). This simple observation sparked a playful numerical challenge for the coming year, 2026. The question isn’t about predicting the future but about exploring the creative possibilities within mathematics itself.
The Challenge Unveiled
The core puzzle involves finding expressions that equal 26 using a limited set of digits (9s, 8s, 7s, 6s, 5s, 4s, 3s, and 2s) and basic mathematical operations. The allowed tools include addition, subtraction, multiplication, division, brackets, exponentiation (raising a digit to a power), and concatenation (joining digits to form larger numbers).
This isn’t about complex algorithms; it’s about lateral thinking. The puzzle highlights how seemingly simple numbers can be constructed in infinite ways, given the right tools.
Why This Matters
Mathematical puzzles like this aren’t just idle entertainment. They demonstrate the fundamental nature of numbers and how they can be manipulated to reveal hidden patterns. This kind of thinking translates to problem-solving in any field, from engineering to finance. More broadly, it reinforces the idea that creativity and logic are not mutually exclusive.
The Solutions (Delayed)
The author will reveal the solutions at 5 PM UK time. The request for no spoilers is a nod to the collaborative nature of these puzzles—the joy is in the struggle, not just the answer. Instead of cheating, participants are encouraged to share what they enjoy about the number 26 itself.
Further Exploration
For those interested in deeper numerical curiosities, the author references the work of Inder Taneja (numbers-magic.com), who has explored the properties of 26 and 2026 in detail. This suggests there’s a rich world of number theory beyond the basic puzzle, waiting to be discovered.
In conclusion, the 2026 puzzle is a lighthearted but revealing exploration of mathematical creativity. It reminds us that even the simplest numbers hold endless possibilities, and that sometimes, the journey to the solution is more valuable than the answer itself.
