A new teaser goes viral on X

One of the latest mind-bending puzzles to grab attention online was shared on X (formerly Twitter) by user @jitendra789789. The puzzle reads:

6 + 9 = 61, 5 + 8 = 46, 4 + 7 = 33, 3 + 6 = ?

At first, the equations appear mathematically incorrect when viewed through the lens of conventional arithmetic. However, there’s a hidden logic behind them that is leaving even the most enthusiastic problem-solvers puzzled.

An earlier riddle that left the internet guessing

This is not the first time such a teaser has gone viral. Previously, another mathematical riddle shared by the account Brainy Quiz created a buzz online. It read:

“I am a number. Multiply me by 4, then subtract 6. The result is 18. What number am I?”

Though simpler in format, this riddle still made people pause and rethink their basic arithmetic. Many users confidently attempted to solve it, some correctly identifying the answer as 6, while others overcomplicated the equation.
