Challenges and brain teaser IQ tests are fantastic ways to boost your mind power and improve cognitive function.

When you accept a challenge, it forces you to think outside of the box and test your abilities in the form of a challenge.

I take another test called the matchstick puzzle which they provide not only fun but also highly educational because it encourages the mind that if you have thinking skills, solve the problem.

The test is to solve the matchstick equation and correct the answer in 6 seconds!

**The Challenge**

As you see in this particular matchstick equation, you are presented with an equation made entirely of matchsticks: **9 + 9 = 9**.

At first glance, the equation seems incorrect but the challenge is to make the equation correct by moving just one matchstick.

You have only 6 seconds to figure it out.

This time limit adds an extra layer of difficulty, making the puzzle not only a test of intelligence but also of quick thinking.

Now, let’s dive into solving the puzzle. The key to solving matchstick puzzles lies in careful observation and thinking **outside the box**. Here’s a step-by-step approach to solve this particular puzzle:

**Analyze the Equation:**Look at each part of the equation:**9 + 9 = 9**. Clearly, the equation as it stands is incorrect because 9 + 9 equals 18, not 9.**Consider Possible Moves:**You are allowed to move only one matchstick. Think about how moving one matchstick could change the equation to make it correct.**Visualize Changes:**Visualize moving one matchstick from the numbers or the operator to form a new equation.

In this puzzle, the solution is to move one matchstick from one of the 9s on the left side of the equation to turn it into a different number or symbol.

**Move the vertical matchstick from the leftmost 9 to create a 3.**

Now the equation reads: **3 + 9 = 9**, which is clearly incorrect because 3 + 9 equals 12, not 9. So, this isn’t the solution.

The actual correct move is:

**Move the vertical matchstick from the plus sign (+) to turn it into a minus sign (-).**

Now the equation reads: **9 – 9 = 0**. This is a correct equation because 9 minus 9 does indeed equal 0.
