The latest brain teaser, shared on the platform X by the account Brainy Bits Hub, presents four basic equations. The teaser begins with a sequence showing values for each letter: “M + M = 20,” “N + N = 10,” and “O + O = 8.” The final equation, however, is where the challenge lies: “What is M + N × O = ?”
With nearly 5k views and counting, the post has generated lively discussion as users debate the answer and question each other’s logic. The puzzle is deceptively simple, requiring only basic operations, yet it has puzzled many who attempt to solve it.
Social media users have shared their thoughts on the puzzle, with some claiming it’s easy while others express frustration at the misleading simplicity.

Took me a few tries, but I finally cracked it.”
Others, however, weren’t as successful in their attempts. “I’ve tried every possible calculation, but I just can’t get it right,” one frustrated commenter admitted, adding a few laughing emojis to express their disbelief. Another user shared, “I was so sure my answer was correct, but now I’m not even sure if I’m doing basic math correctly anymore.”
