Step 2: Rewrite the expression clearly
We start with:
5 × 5 – 5 + 5 ÷ 5
Now we focus only on multiplication and division first.
Step 3: Solve multiplication and division
First:
5 × 5 = 25
Then:
5 ÷ 5 = 1
Now the expression becomes:
25 – 5 + 1
Step 4: Solve left to right (addition and subtraction)
Now we go step by step from left to right:
Step 1:
25 – 5 = 20
Step 2:
20 + 1 = 21
Final Answer:
5 × 5 – 5 + 5 ÷ 5 = 21
Why people get it wrong
Most mistakes happen when people:
- Solve strictly left to right without rules
- Ignore division priority
- Try to “mentally simplify” too fast
- Get tricked by the simplicity of the numbers
The puzzle is not about intelligence—it’s about discipline in following mathematical rules.
The real “genius trick”
The trick behind this boarding pass puzzle is psychological. It looks easy, so people rush. But the correct solution only appears when you slow down and apply structured thinking.
That’s why these puzzles go viral—they test attention to process, not intelligence.
Final takeaway
Whenever you see expressions like this:
- Don’t rush
- Always apply order of operations
- Solve multiplication/division first
- Then go step by step
Because in math, precision beats intuition.
