🧩 Puzzle Answer: What Is the Result of 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 × 0?
Did you choose 0, 9, 45, or 90?
This puzzle tricks thousands of people because most of us instinctively add the numbers from left to right without thinking about the order of operations.
Let’s solve it correctly!

Step 1: Remember the Order of Operations
In mathematics, multiplication is always performed before addition.
This means we must calculate:
9 × 0 = 0
before adding anything else.
Step 2: Replace the Multiplication
The expression becomes:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 0
Now add the remaining numbers:
- 1 + 2 = 3
- 3 + 3 = 6
- 6 + 4 = 10
- 10 + 5 = 15
- 15 + 6 = 21
- 21 + 7 = 28
- 28 + 8 = 36
So the final answer is:
✅ Correct Answer: 36
Why Do So Many People Get It Wrong?
Many people ignore the multiplication rule and simply add everything together first:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45
Then they multiply by zero mentally—or worse, forget the multiplication entirely.
Others see the × 0 and immediately answer 0, forgetting that only the 9 is multiplied by zero, not the entire expression.
That’s exactly why this puzzle is so deceptive!
💡 Quick Math Tip
Always remember this simple rule:
- Parentheses
- Exponents
- Multiplication and Division
- Addition and Subtraction
Since multiplication comes before addition, calculate 9 × 0 first.
Final Calculation
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 × 0
= 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 0
= 36 ✅
