Step 3: Move Left to Right for Multiplication and Division
A common mistake is doing multiplication before division automatically. In reality, you go left to right.
Now solve:
- 48 ÷ 6 = 8
- 8 × 8 = 64
Step 4: State the Final Answer
Final answer: 64
Done in under 10 seconds once the method becomes automatic.
Another Example (Slightly Tricky)
100 − 20 ÷ 5 × 2 = ?
Step 1: Division and multiplication first (left to right)
- 20 ÷ 5 = 4
- 4 × 2 = 8
Now the expression becomes:
100 − 8
Step 2: Final subtraction
- 100 − 8 = 92
Final answer: 92
The Real “Secret” Behind These Puzzles
There is no hidden genius trick. Fast solvers simply:
1. Recognize the pattern instantly
They don’t re-read the expression multiple times.
2. Follow order-of-operations automatically
PEMDAS becomes second nature.
3. Avoid common traps
Most mistakes come from:
- Doing addition before multiplication
- Ignoring left-to-right rules
- Rushing without structuring the problem
How to Train Yourself to Solve in 10 Seconds
If you want to get faster, practice like this:
- Start with simple 2-step expressions
- Gradually add parentheses
- Time yourself (10–15 seconds per problem)
- Repeat until the process feels automatic
Example practice set:
- 12 ÷ 3 + 7 × 2
- (15 − 5) × 4
- 81 ÷ 9 × (2 + 1)
Final Thoughts
These “only geniuses can solve it” puzzles are really just tests of speed and pattern recognition—not intelligence. Once you understand the structure and practice enough, you’ll be solving them just as fast as anyone else.
So the real question isn’t “Are you a genius?”
It’s “Do you know the method?”
If you want, I can give you a set of timed puzzles (easy → hard → trick level) to train your brain for 10-second solving.
