You might think this math problem is straightforward — just simple subtraction, multiplication, and addition with easy numbers.
But what if I told you that this puzzle has been fooling thousands online? Beneath its innocent-looking surface lies a tricky detail many overlook, causing even quick math whizzes to stumble. Could you be falling for the same hidden pitfall? Let’s take a closer look before you rush to answer.
Viral Math Puzzle: Why It’s More Complicated Than It Seems
Math puzzles are making a major comeback on social media, and one particular equation is catching eyes due to its simplicity — and its surprising difficulty. The problem is straightforward at first glance, but it has a sneaky twist that trips up many.
The Puzzle:
11−11×11+11=?
On the surface, it looks like basic arithmetic. Small numbers, familiar operations — subtraction, multiplication, and addition. So why does this simple-looking question confuse so many?
Step-by-Step Breakdown Using Order of Operations
To solve correctly, you must follow the universally accepted rules known by the acronym PEMDAS, which helps us remember the order:
P: Parentheses first
E: Exponents next
MD: Multiplication and Division, from left to right
AS: Addition and Subtraction, from left to right
Let’s apply these to the puzzle:
Multiply first:
11×11=121
Substitute this back in:
11−121+11
Now proceed left to right:
11−121=−110
−110+11=−99
Final Answer:
−99
Why Do So Many People Get It Wrong?
The puzzle’s trick lies in how our brains look for patterns. Seeing “11” repeated so often tempts us to simplify incorrectly or solve the problem straight left to right, ignoring multiplication precedence. This leads to wrong answers like 0, 11, or even 121.
It’s a classic reminder that solid math rules like PEMDAS exist for a reason — especially when problems look deceptively simple.
✅ Conclusion: Slow Down and Trust the Rules
Fun math puzzles like this aren’t just brain teasers — they’re practical lessons on why following order of operations matters. Even if you don’t consider yourself a math expert, remembering PEMDAS can save you from common mistakes and keep you sharp.
Next time you spot an “easy” math problem, pause and think before you solve. Follow the rules carefully, and enjoy the satisfaction of cracking the puzzle right.
