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!

A POOR BOY SAVED A RICH MAN’S LIFE—THE NEXT DAY, HE AND HIS ILL MOTHER FOUND A BAG SENT BY THAT SAME MAN ON THEIR PORCH.

The dust of the country road swirled around Martin’s worn sandals as he trudged home, his stomach growling with the familiar pangs of hunger. He was a wisp of a boy, barely ten years old, with eyes that held the weight of too many hardships. His mother, frail and perpetually ill, relied on him for everything, from gathering firewood to earning meager coins from odd jobs.
As he rounded a bend, a sleek, black automobile roared past, kicking up a cloud of dust that stung his eyes. He coughed, waving his hand to clear the air, and then noticed the car had stopped further down the road. It was angled awkwardly, half on the pavement, half in the ditch. A figure slumped inside.
Curiosity piqued, Martin ran towards the car. Inside, a man, dressed in fine clothes, was choking, his face turning an alarming shade of purple. He was clutching his throat, his eyes wide with panic. Martin recognized him; it was Sylvester Thorne, the wealthy landowner whose grand estate loomed over their humble village.
Without hesitation, Martin grabbed a rock from the roadside and smashed the car window. Glass shattered everywhere as he reached in to unlock the door. “Stand back!” he shouted, pulling Sylvester out onto the pavement.
Sylvester was gasping, his hands still clutching his throat. Martin knew he had to act quickly. He remembered a trick he’d seen his father use once, a desperate measure. With all his might, Martin delivered several sharp blows to Sylvester’s back. Suddenly, a chunk of apple flew from Sylvester’s mouth, and he gasped for air, his lungs finally filling with air.
The rich man looked at the boy with tears in his eyes and kept thanking him for saving his life, his voice hoarse. “You… you saved my life, boy. I… I owe you everything.”
Martin, flustered by the man’s gratitude, simply nodded. “Just glad you’re alright, sir.” And then, he turned and walked away, his stomach still growling, his mind already turning to the task of finding something for his mother to eat.
The next morning, Martin was jolted awake by his sister, Lily’s, excited screams. “Marty! Marty! Come quick!”
He rushed outside, his mother calling after them in confusion, her voice weak but laced with concern. There, on their doorstep, sat a large, brown bag. It was tied with a silken ribbon, a stark contrast to the rough, worn wood of their porch.
Lily, her eyes wide with wonder, tugged at the ribbon. Martin cautiously untied it, and the contents spilled out: a loaf of fresh bread, a basket of plump, red apples, a jar of honey, and a small pouch filled with coins. At the bottom of the bag, a folded note lay nestled amongst the food.
Martin unfolded it, his eyes scanning the elegant script. “To Martin, for your bravery and kindness. From Sylvester Thorne.”
His mother, her face etched with a mixture of relief and astonishment, reached for the bread, her fingers trembling. “It’s from Mr. Thorne,” Martin said, his voice hushed. “He remembered.”
The food was a godsend. They hadn’t had a proper meal in days. The coins, though few, were enough to buy medicine for his mother and some seeds for their small garden. But it was more than just the material goods. It was the knowledge that someone, especially someone as powerful as Sylvester Thorne, had seen their plight and cared.
News of Martin’s heroism spread through the village like wildfire. People who had once turned a blind eye to their poverty now offered smiles and words of encouragement. Even the gruff baker, who had always refused them credit, gave them a warm loaf of bread and a wink.
Sylvester Thorne, true to his word, didn’t forget Martin. He visited their small cottage, his presence filling the cramped space with an air of grandeur. He spoke to Martin’s mother, his voice gentle and respectful. He offered to pay for her medical treatment and to send Martin to school.
Martin, overwhelmed by the man’s generosity, looked at his mother, her eyes shining with hope. She nodded, her lips forming a silent “yes.”
Life changed for Martin and his family. His mother’s health improved, and he excelled in school, his sharp mind eager to learn. He never forgot the day he saved Sylvester Thorne, nor the kindness that followed. He understood that even in the midst of hardship, a single act of courage and compassion could change everything. And Sylvester Thorne, in return, learned that true wealth wasn’t measured in possessions, but in the lives he touched and the gratitude he received.
