Matchstick puzzles have entertained and challenged people for generations. They test our ability to think critically, manipulate numbers, and spot patterns that others might miss. If you love a good brain teaser, this puzzle will put your skills to the test.
Your goal is to fix the following equation by moving just one matchstick:
22 – 9 + 8 + 13
Something is not quite right…
At first glance, this equation appears to be fine—there are numbers and mathematical symbols in the correct places. However, when you perform the calculations, the final result doesn’t add up correctly.
Let’s break it down:
First, subtract 9 from 21:
22 – 9 = 11
Now, add 8:
11 + 8 = 19
Finally, add 13:
19 + 13 = 22
However, the equation appears to be structured in a way that suggests a different answer. Clearly, something is incorrect, and a small adjustment is needed.
The challenge: Fix it with a single move
The rules are simple: You can move just one matchstick to make the equation correct. That means you cannot remove or add extra numbers, nor can you shift multiple matchsticks at once.
So, where should you focus? Sometimes, the trick lies in changing a number. Other times, modifying an operator (such as +, -, or =) is the key to solving the puzzle.
Take a moment to analyze the equation carefully. Which number or symbol looks like it could be adjusted to fix the equation?
Common mistakes people make
Before we reveal the solution, let’s explore some of the common errors people make when tackling matchstick puzzles:
1. Trying to move more than one matchstick: Since the challenge only allows one move, changing multiple elements at once is not the right approach.
2. Ignoring the mathematical symbols: Many people focus only on the numbers and forget that modifying an operator can sometimes be the key to solving the puzzle.
3. Overthinking the solution: The best solution is often a simple one. Sometimes, a small change can make a big difference.
The solution: Did you figure it out?
If you’ve thought it through and believe you have the answer, let’s see if you’re correct.
The correct move is:
Remove the middle vertical matchstick from the number 8 and place it vertically on top of the minus sign.
This small adjustment changes the 8 into a 0 and transforms the minus sign into an equals sign.
Now, let’s look at the corrected equation:
22= 9 + 0 + 13
Final thoughts
