Matchstick puzzles are a great way to test your problem-solving skills. They challenge you to think outside the box and find a simple yet clever solution to what seems like an incorrect equation. In this puzzle, you are given a mathematical equation that is not quite right, and your task is to fix it by moving just one matchstick. Sounds simple, right? Let’s see if you can figure it out!

Take a look at the following equation:

2 + 15 – 3 = 1 – 13

What’s Wrong With This Equation?

At first glance, everything might look fine, but when you do the math, you’ll notice a problem. Let’s break it down step by step.

First, calculate the left-hand side:

2 + 15 = 17

17 – 3 = 14

Now, calculate the right-hand side:

1 – 13 = -12

Clearly, 14 ≠ -12, which means the equation is incorrect. But how can you fix it by moving only one matchstick?

The Challenge: Fix It With a Single Move

Remember, you are only allowed to move one matchstick. No adding or removing extra sticks—just a single move. You need to find the matchstick that, when moved, transforms the equation into a correct one.

Sometimes, the trick is to focus on the numbers, while other times, the issue lies in the mathematical operators. If you look closely, you might notice that one of the symbols can be adjusted in a way that makes the equation valid.

Common Mistakes People Make

Before we reveal the solution, let’s look at some common mistakes people make when solving matchstick puzzles like this one:

1. Trying to Move More Than One Matchstick: It’s tempting to think that two changes are needed, but remember, the challenge requires only one move.

2. Overlooking the Mathematical Operators: Many people assume they need to change a number when, in fact, modifying a plus, minus, or equals sign can be the key to solving the puzzle.

3. Rushing to Find a Solution: Sometimes, taking a step back and looking at the equation from a fresh perspective helps. The answer is often simpler than it first appears.

The Solution: Did You Get It Right?

Now that you’ve had some time to think, it’s time to reveal the solution.

The correct move is:

Remove one of the vertical matchsticks from the equals sign (=) and place it vertically on top of the last minus sign (-).

This change does two things:

1. The equals sign (=) becomes a minus (-).
2. The last minus sign (-) becomes an equals sign (=).

Now, the corrected equation reads:

2 + 15 – 3 – 1 = 13

Conclusion: A Small Change Can Make a Big Difference

It’s amazing how a tiny adjustment can completely change an equation. These puzzles are a great way to sharpen your logical thinking and attention to detail. If you solved it on your own, well done! If not, don’t worry—there are plenty more matchstick challenges to test your skills.
