Matchstick puzzles challenge your ability to think logically and creatively. They present seemingly incorrect equations that can be fixed by moving just one matchstick. While the solution is simple, finding it can be quite tricky! Let’s see if you can crack this puzzle.
The given equation is:
73 – 9 + 6 – 2
What’s Wrong With This Equation?
At first glance, the equation might seem fine, but when you calculate the numbers, you’ll notice a problem.

Breaking it down step by step:
73 – 9 = 64
64 + 6 = 70
70 – 2 = 68
The equation currently gives us 68, but something is clearly wrong. The numbers don’t match up with what the equation is supposed to represent. The challenge is to fix it by moving just one matchstick.
The Challenge: Fix the Equation in One Move
You can’t add or remove matchsticks—just shift one to a new position. The key is figuring out which part of the equation should be changed to make it correct. Will it be a number or an operator? You might be surprised by how small the adjustment needs to be.
Look closely at the numbers and the signs. Sometimes, a simple transformation can make a big difference. Could adjusting a digit create a correct equation? Or is the issue in the mathematical symbols?
Common Mistakes People Make
Matchstick puzzles are tricky because they play with our visual perception. Here are some common mistakes:
1. Assuming a Complex Change Is Needed: The key to solving matchstick puzzles is simplicity. People often overthink and look for elaborate solutions instead of simple ones.
2. Ignoring the Operators: Sometimes, the problem isn’t with the numbers but with the mathematical signs.
3. Trying to Move More Than One Matchstick: The challenge allows only one move. Making multiple adjustments would make it too easy!
Have You Found the Answer?
Before we reveal the solution, take another look at the equation. Can you spot which matchstick needs to move?
The Solution: Here’s the Correct Equation
The trick is to focus on the first number, 73. By removing the vertical matchstick from the 7 and placing it vertically on top of the first minus sign, we create a simple yet effective change:
1. The 7 turns into a 1.
2. The minus sign (-) turns into an equals sign (=).
Now, the equation becomes:
13 = 9 + 6 – 2
Conclusion: A Small Move, a Big Difference
With just one simple move, the incorrect equation is transformed into a valid mathematical statement. Matchstick puzzles like this one teach us the importance of paying attention to detail and thinking outside the box. Did you manage to solve it? If so, congratulations! If not, don’t worry—these puzzles take practice.
