What if a simple calculation could sow doubt in the minds of thousands of people? On social media, a seemingly basic equation sparked a real debate. Some were certain of their answer\u2026 before realizing they were wrong. So, was it a trap or a simple oversight? You might be surprised by the answer.<\/p>\n
This calculation that makes everyone doubt
\nHere\u2019s the equation that\u2019s driving the internet crazy:<\/p>\n
3 \u00d7 3 \u2212 3 \u00f7 3 + 3<\/p>\n
At first glance, nothing complicated. Yet, many fall into the trap by going too fast.<\/p>\n
Some people read the expression from left to right without thinking it through. Result: an incorrect answer.<\/p>\n
And that\u2019s where everything happens.<\/p>\n
Why do we make mistakes so easily?<\/p>\n
The problem does not stem from the calculation itself, but from the method used.<\/p>\n
When faced with a series of operations, our brain tends to go for the simplest solution: calculating in the order of reading.<\/p>\n
But in mathematics, there is one essential rule to follow. And that\u2019s what makes all the difference.<\/p>\n
The rule you absolutely need to know
\nTo avoid errors, a rule called order of operations (or BODMAS \/ PEMDAS depending on the country) is used.<\/p>\n
It defines the order in which to perform the calculations:<\/p>\n
Parentheses
\nOrders (powers)
\nMultiplication and division (from left to right)
\nAddition and subtraction (from left to right)
\nIn other words, we don\u2019t calculate everything in order\u2026 but according to a precise logic.<\/p>\n
Let\u2019s solve it together, step by step.
\nLet\u2019s now apply this rule to our equation:<\/p>\n
We begin with multiplication and division:
\n3 \u00d7 3 = 9
\n3 \u00f7 3 = 1<\/p>\n
The equation therefore becomes:
\n9 \u2212 1 + 3<\/p>\n
We finish with addition and subtraction:
\n9 \u2212 1 = 8
\n8 + 3 = 11<\/p>\n
Final result: 11<\/p>\n
Why is this type of calculation going viral?<\/p>\n
This kind of equation works perfectly on social media for one simple reason: it plays on our automatic responses.<\/p>\n
We think we have the right answer in a few seconds\u2026 but without correctly applying the rules, the error is almost inevitable.<\/p>\n
And it is precisely this little trap that makes these challenges so popular.<\/p>\n
An excellent exercise to keep the mind sharp
\nBeyond the hype, this type of problem also has a very positive side.<\/p>\n
He reminds us of the importance of taking the time to reflect, even when faced with something that seems obvious. A good way to stimulate your brain and revisit basic concepts that are sometimes forgotten.<\/p>\n
And between us, admit it, it always feels good to succeed at a little challenge like this.<\/p>\n
Sometimes, the simplest calculations are the ones that remind us that a little method is better than rushing. Simple tip<\/p>\n","protected":false},"excerpt":{"rendered":"
