Did you solve it? Are you ready for twenty twenty-six…seven? | Mathematics

Earlier today, I offered you the following series of digital challenges to celebrate the arrival of 2026.

Signs of Auld Lang

Here is an expression equal to 26 that uses six 1s:

(1+1)×(1+1+11)

Find expressions equal to 26 using:

You are only allowed the four basic operations, +, –, x, ÷, parentheses, exponentiation and concatenation. (Exponentiation involves making a number the exponent, such as 1¹. Concatenation involves joining numbers together, for example taking two 1s and making 11.)

Solutions

9+9+9−(9/9)

8+8+8+((8+8)/8)

7+7+((77+7)/7)

6×6+(6−66)/6

5×5+(5/5)

4+(44×4/(4+4))

3³ − 3/3

22 + 2 + 2

Good news everyone! I will be back in 7+7+((77+7)/7)

Thanks to Inder Taneja, author of the site number-magic.com. He has a lot more facts about the coming year in his article 26 and 2026 in Magic Numbers and Squares.

I’ve been putting up a puzzle here every other Monday since 2015. I’m always looking for great puzzles. If you want to suggest one, send me an email.
