In other words, we don't count everything in order... but according to precise logic.
Let's solve this together, step by step.
Now let's apply this rule to our equation:
Let's start with multiplication and division:
3 × 3 = 9
3 ÷ 3 = 1
So the equation becomes:
9 − 1 + 3
We end up adding and subtracting:
9 − 1 = 8
8 + 3 = 11
Final result: 11
Why is this type of calculation going viral?

This kind of equation works perfectly on social media for one simple reason: it plays on our automatic reactions.
We think we have the correct answer in a few seconds… but without proper application of the rules, error is almost inevitable.
And it's this little trap that makes these challenges so popular.
Excellent exercise to keep your mind sharp
Besides the hype, this type of problem also has a very positive side.
It reminds us of the importance of taking time to reflect, even when faced with something that seems obvious. It's a good way to stimulate the brain and remind ourselves of basic concepts that are sometimes forgotten.
And between us, admit it, it always feels good to succeed in such a small challenge.
Sometimes the simplest calculations are the ones that remind us that a little method is better than rushing. A simple tip
