If you’re a fan of perplexing maths riddles, this brain teaser is bound to stretch your problem-solving skills to their limits. Posted by user @brain_teaser_1 on X, the puzzle has quickly gone viral, inviting both curiosity and frustration from the online community. Unlike standard arithmetic problems, this teaser plays with numbers in an unconventional way, encouraging users to think beyond basic calculations.
An unexpected challenge for even the sharpest minds
While the puzzle starts with familiar maths operations, the results on the right-hand side deviate from conventional rules. The left column shows numbers (4, 5, 6, and 8) that appear to be squared, but the answers are not the expected square values. Instead, a hidden logic manipulates the digits in an unusual manner, challenging participants to decode a secret rule that underpins each equation.
