Brain teasers continue to dominate social media, and the latest one making rounds is all about how well you understand simple maths instructions. While the numbers involved may seem basic, it’s the phrasing that adds complexity highlighting how easily the mind can be misled by everyday words.

The riddle
A fresh puzzle shared by Facebook user Arshdeep Soni has sparked widespread interest among puzzle lovers and casual scrollers alike. The teaser states:
"Divide 100 by half, then add 50, then subtract 20, multiply by 5."
The challenge lies not in solving complex equations, but in interpreting the operations correctly. These types of puzzles often trip people up because of the way they are worded.

A familiar format reappears on social platforms
This is not the first time such a puzzle has captured attention. A similar teaser previously posted on X (formerly Twitter) by user Ganesh UOR followed a nearly identical format. That version read:
"Divide 90 by half and then add 25. Only genius will answer."
Both puzzles rely on the reader’s interpretation of the language rather than purely on mathematical skill. By using everyday phrasing with unexpected outcomes, they invite people to engage, discuss, and challenge one another.
Why maths teasers thrive on social media
Part of what makes these brain teasers so successful is their ability to appear simple while being cleverly deceptive. They don’t require advanced knowledge—just careful attention. This makes them perfect for sharing, debating, and even arguing over in comment sections across platforms.
