Calculate the sum of all horizontal and vertical two-digit numbers. (Answer: Horizontal: 78, 94. Vertical: 79, 84. Total = 335.)
12 + 23 + 45 + 56 + 78 + 89 + 14 + 47 + 25 + 58 + 36 + 69 = ? meximath
Meximath is unique because a 5-year-old can attempt it (by pairing numbers visually), but a mathematician can explore its combinatorial properties (how many pairs in an n x n grid? The formula is 2n(n-1) ). As of 2025, Meximath shows no signs of slowing down. App developers have created "Meximath Generators" that produce infinite puzzles. Coding challenge platforms like LeetCode and HackerRank have seen user-submitted "Meximath Solver" problems where you must write a Python or JavaScript function to compute the sum.
