Matchstick puzzles are a great way to test your problem-solving skills. They require a sharp eye, logical thinking, and a bit of creativity to find the right move. In this challenge, you are presented with an incorrect equation made from matchsticks, and your task is to fix it by moving just one matchstick.
Think you can do it? Let’s put your skills to the test!
The Puzzle: An Incorrect Equation
Here is the equation you need to fix:
19 – 3 + 18 = 2
At first glance, this equation seems completely wrong. If you calculate it:

19 – 3 = 16
16 + 18 = 34
34 is definitely not equal to 2! Clearly, something needs to change.
The Challenge: Fix the Equation in One Move
Here’s the tricky part: you can move only one matchstick. That means you must carefully examine the numbers and the symbols to determine the best move. The goal is to transform the incorrect equation into a correct one without adding or removing any additional matchsticks.
Look closely at the numbers and the operators. Does a small change to one of them result in a valid equation?
Common Mistakes in Matchstick Puzzles
Before we reveal the solution, here are a few common errors people make when solving matchstick puzzles:
1. Trying to Move More Than One Matchstick: The challenge only allows one move. If you find yourself making multiple changes, rethink your strategy.
2. Overlooking the Mathematical Symbols: The mistake may not be in the numbers themselves but in the operators. A small change to a plus or minus sign can completely alter the equation.
3. Ignoring the Simplicity of the Solution: Many matchstick puzzles have deceptively simple solutions. Don’t overthink it—sometimes, the answer is right in front of you.
Take a Final Look Before Seeing the Answer
Before we reveal the correct equation, take another careful look at the matchsticks. Can you spot the one matchstick that needs to be moved?
The Solution: The Corrected Equation
The trick lies in modifying both the minus sign and the equals sign. By removing one vertical matchstick from the equals sign and placing it vertically on top of the first minus sign, you achieve two key transformations:
1. The equals sign (=) becomes a minus (-).
2. The minus sign (-) becomes an equals sign (=).
This changes the equation to:
19 = 3 + 18 – 2
Conclusion: A Small Move, A Big Change
With just one small adjustment, we have turned an incorrect equation into a correct one. This puzzle is a great reminder that sometimes, the smallest details make the biggest difference.
Did you solve it on your own? If so, congratulations! If not, don’t worry—these puzzles are designed to challenge even the sharpest minds. Try sharing it with a friend and see if they can crack it as quickly as you did!
