The puzzle
If you’re a fan of mind-bending puzzles, a new mathematical riddle has surfaced online that’s sure to twist your brain. Shared on X (formerly Twitter) by user @jitendra789789, the puzzle reads:
“2×3 = 36, 3×4 = 144, 4×5 = ?”
Check out the puzzle here:
At first glance, the equations appear blatantly incorrect — after all, 2×3 is 6, not 36, and 3×4 is 12, not 144. But that’s exactly what makes the puzzle intriguing. This isn’t a simple maths question; it’s a riddle disguised as arithmetic. The real challenge lies not in performing basic multiplication but in deciphering the hidden logic that turns these ordinary expressions into extraordinary results.
Another puzzle
Previously, X user Laura Michelle shared a seemingly straightforward equation that left many scratching their heads:
“Without a calculator, just your brain, solve this: 60 + 20 + 6 - 10 × 0 = ?”
While some rushed through the sum, ignoring mathematical rules, others correctly followed the order of operations — revealing just how deceptive such puzzles can be. The simplicity on the surface often masks a trap for the unwary, making these puzzles both entertaining and unexpectedly tricky.
The internet’s obsession with puzzles continues
Social media platforms like X and Reddit have become hotspots for viral challenges like these. Users enthusiastically share, debate, and compete to crack the code first. The mix of logic, surprise, and collective curiosity keeps millions engaged.
