Mathematicians and Number Lovers Rejoice: The Quest Begins for Twenty-Six
As we bid farewell to 2025, a unique year in our century due to its square number status, we're left with an intriguing mathematical challenge. The year itself can be expressed as the sum of two squares, namely 44^2 = 1936 and 45^2 = 2025. But what's next? The number 2026 is just around the corner, and with it comes a puzzle that will put our math skills to the test.
The puzzle in question asks us to find an expression equal to 26 using only the four basic operations (+, -, x, ÷), brackets, exponentiation, and concatenation. But there's a twist: we can use different numbers of digits, as long as they're all single-digit numbers. Think you're up for the challenge?
The original puzzle offers several hints, including expressions that equal 26 using five 9s, six 8s, six 7s, six 6s, four 5s, six 4s, four 3s, and four 2s. But don't worry if you get stuck - no spoilers here! We want to hear from you about what you love most about the number 26.
Math enthusiasts will appreciate the fact that this puzzle is inspired by Inder Taneja's paper "26 and 2026 in Numbers and Magic Squares." If you're as fascinated by numbers as we are, check out his website, numbers-magic.com. And if you have a great puzzle suggestion for our journalist-in-residence, email us! We'll be back with the solutions at 5pm UK time, but first, let's enjoy this mathematical quest together and share your favorite things about the number 26.
