The puzzle

The Facebook page Minion Quotes recently shared a puzzle that has been puzzling online users — but in the most entertaining way. The teaser reads:

"Math Puzzle: 10 + 10 = 00, 12 + 13 = 36, 13 + 13 = 39, 15 + 14 = ?? — Can you solve this?"

Check out the puzzle here:

On the surface, the equations look entirely incorrect. But that’s exactly what makes them so engaging. There’s a pattern buried within the madness — and users are determined to uncover it. From applying advanced maths to making wild guesses, the comment section is filled with possible solutions.

A similar puzzle took over X earlier

Earlier, a brain teaser posted by the account Brainy Quiz on X (formerly Twitter) also caught the attention of puzzle enthusiasts. Here’s how it goes:

"1 + 4 = 5, 2 + 5 = 12, 3 + 6 = 21, 8 + 11 = ?"

Once again, traditional arithmetic doesn’t seem to apply. Yet, there’s a clever trick hidden within the equations — and figuring it out is surprisingly satisfying.
