Are you ready to challenge your brain with a fascinating math puzzle? At first glance, the equation in the image may look like a simple addition problem, but there’s a hidden pattern that makes it more complex than you think.
Take a moment to analyze the given equations:
- 9 + 2 = 711
- 14 + 6 = 820
- 17 + 11 = 628
- 12 + 3 = ???
Can you figure out the logic behind these numbers and find the correct answer? Give it a try before scrolling down for the solution!

Common Mistakes People Make When Solving This Puzzle
Many people approach this problem using traditional math rules. Since the equations involve addition, they naturally assume the answer follows basic arithmetic. However, these numbers don’t add up conventionally, leading to confusion.
Here are some common errors people make:
Trying to use standard addition – When adding 9 + 2, the result should be 11, but the puzzle gives 711 instead. Clearly, something else is happening.
Assuming a hidden multiplication or division – Some people think there’s a multiplication or division pattern involved, but that doesn’t explain all the numbers.

Overcomplicating the logic – Sometimes, the best approach is to look for a simple pattern instead of forcing complex mathematical operations.
If you’re stuck, don’t worry! Let’s break it down step by step and uncover the hidden pattern behind these numbers.
Step-by-Step Guide to Solving the Puzzle
To understand the logic behind these equations, let’s analyze how the numbers are structured.
Step 1: Look for a Pattern in the Results
Instead of performing normal addition, let’s break down each result:
- 9 + 2 = 711
- 14 + 6 = 820
- 17 + 11 = 628
Notice that each result consists of three digits. What could these numbers represent?
Step 2: Identify the Hidden Logic
Let’s analyze the relationship between the input numbers and the output:
- The first digit of the result seems to come from the sum of the two numbers.
- The last two digits of the result seem to come from the product of the two numbers.
Let’s verify this theory:
- 9 + 2 = 11, 9 × 2 = 18 → But the result is 711?
- Instead of 18, it looks like the product’s last two digits are considered.
- If we write 11 first, but take only the last two digits of 9 × 2 = 18, we get 711.
- 14 + 6 = 20, 14 × 6 = 84 → The result is 820.
- First part: Sum = 20
- Second part: Product = 84
- The final number is 820 (placing 20 first, followed by 84).
- 17 + 11 = 28, 17 × 11 = 187 → The result is 628.
- First part: Sum = 28
- Second part: Product = 187, taking the last two digits 87
- The final result is 628.
Step 3: Apply the Logic to the Missing Equation
Now, let’s use this pattern to solve 12 + 3 = ???
- Sum:
- 12 + 3 = 15
- Product:
- 12 × 3 = 36
- Final Answer:
- By following the discovered pattern, we place the sum first, followed by the last two digits of the product:
- 12 + 3 = 915
Final Answer: 915
So, the correct answer to the puzzle is 915!

WHO IS THIS ACTOR, WHO WAS LIVING WITH $150 A MONTH, AND NOW HAS A FARM WITH HIS FAMILY
Renowned in the movie industry, this actor recently clinched a Golden Globe for his standout performance in an HBO project. Surprisingly, prior to his foray into television, he had never actually watched any of his own performances.
In a candid interview, he confessed his initial skepticism towards TV projects, stating: “If my agent had called me and said, ‘I think you should do a series,’ I would have fired my agent…”
However, it was his actress wife who ultimately persuaded him to reconsider. He fondly recalled the joy of sharing the screen with her and attending award ceremonies together.
Reflecting on his wife’s versatile acting career, he drew inspiration from the legendary Meryl Streep, noting: “You know, when I started to see her film work, you know, she does one part, and then she does another part, and it’s like barely recognizable, and to me, that was what I had always envisioned being an actor was, to be able to put on these different hats and become different people”.
This accomplished actor, none other than the charismatic 65-year-old Kevin Bacon, has journeyed from struggles to stardom, finding solace and happiness alongside his wife.
During a recent chat with Kelly Clarkson, Bacon reminisced about his humble beginnings. In 1976, he made the leap from Philadelphia to New York, where he had previously visited with his sister.

Arriving in the Big Apple, Bacon initially bunked with his sister until he could secure his own place. With just $150 to his name for the month, he stumbled upon a makeshift living situation advertised in The Village Voice. “Artists, actors, musicians, residents” were welcomed, and he found himself in what he describes as “basically a flophouse”.
For four years, he shared a space with a pianist in a rental office, unable to afford a proper apartment. Despite the challenges, Bacon’s determination and talent eventually paved the way to success, leading him to cross paths with his future wife, Kyra Sedgwick.
Their serendipitous encounter occurred in 1987 on the set of “Lemon Sky”. Bacon was smitten from the start, though Sedgwick needed a bit more convincing. After some persistence, their first date unfolded, marked by laughter and a deep connection that sealed their fate.
“We’ve always been each other’s biggest support and fans. A sense of humor is crucial. He is very freaking funny”, Sedgwick fondly remarked.
Together, they navigated the journey of parenthood, raising two children, Travis and Sosie, who are now adults. For Bacon, being a father is paramount, as he strives to instill values of honesty, integrity, and compassion in his children, emphasizing the importance of caring for the world and each other.
