A 37-year-old man by the name of Simon Marks discovered something quite odd. In other words, he has been residing in the same home for a while, but he only lately realized that he was unaware of what was concealed in the home he had purchased a few years prior.

One day, he came upon what he thought to be a flowerbed while attempting to park his car. His car’s wheels became stuck, and from the driveway, he could hear odd cracking sounds.
He said to himself, “Well, this day couldn’t get any worse.”
Marks bent down to investigate the problem more closely and saw that the driveway’s stones had cracked, causing the driver to give way. The sound of the pavers breaking revealed an incredible finding.

After he had cleared away all the dirt, he saw a metal fragment beneath. Marks clutched the metal piece, not knowing what might be underneath the driveway, and attempted to pull it out, but to no avail. Then he circled around to find out more about the enigmatic thing.
He phoned his father for assistance because he didn’t know what to do next. Together, they were able to remove a large amount of tightly packed muck, which finally revealed an opening. The two men descended the ancient, rusted ladder, curious to see where it would take them.
Marks recalled, “My dad saw it and knew right away that it was an air raid shelter.””After searching on Google, we discovered that there are many in this area.”
The shelter they found in Marks’ garden looked to have been constructed during World War II.
According to Marks, “the previous owner must have known it was there and he must have filled it in when he built the house and put a garden in.”

During the war, these shelters were meant to shield civilians from bombing. It is thought that a guy by the name of Sir John Anderson invented them.

A wall has been sealed with bricks. Though we don’t know, I’m ninety percent certain we won’t discover any more chambers. In order to make room for the foundations when the home was erected, they may have bricked up one of the walls, according to Marks.”We’ll just have to leave it if that’s the case,” he continued.
His discovery was captured on camera, and soon his tale went global.

Marks and his father consider the shelter to be a significant historical landmark, therefore they intend to restore it. They contend that although if that era of history is in the past, it shouldn’t be ignored since it gives us a glimpse into bygone times.
Can You Solve This Tricky Math Puzzle
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!
