Do you think you’re a math whiz? Here’s a matchstick puzzle that will test your problem-solving skills and quick thinking. The challenge is to correct the equation 9-7=1 by adding just one matchstick. You have only 20 seconds to complete this task, so get ready to engage your brain!

The Puzzle: 9-7=1

The equation 9-7=1 needs to be fixed with the addition of one matchstick. It sounds simple, but the time constraint makes it tricky, especially for beginners. For seasoned puzzle solvers, this might feel like a breeze, but it’s still a fantastic way to stimulate your brain and test your logical thinking.

Are you ready to prove your problem-solving skills? Take a close look at the equation and figure out how to correct it. Remember, you have just 20 seconds to make it work. Your mission is to add one matchstick to make the equation correct.

Brain Stimulation and Cognitive Health

This type of puzzle demands quick thinking and sharp reflexes, engaging your neurons in the process. According to research highlighted in Le Figaro, the brain builds and maintains its neural networks through cognitive activity throughout life. Early stimulation helps develop these networks, and continuous use strengthens and maintains them, delaying the onset of neurodegenerative diseases.

Neuropsychologist Jocelyne de Rotrou from Broca Hospital in Paris emphasizes the importance of diverse activities to stimulate different brain regions. Regular engagement in cognitive tasks helps maintain acquired skills, which can regress if not used. Additionally, strategies to enhance brain plasticity are crucial, but they must be supported by good physical and mental health, stress management, and adequate sleep.

Did You Find the Solution?

Social interaction and professional activities also play a vital role in maintaining cognitive faculties, contributing to a “cognitive reserve” that protects against brain aging, according to Professor Françoise Forette.

To solve the puzzle, you need to think creatively. The key is to transform the number 9. By adding one matchstick to the top left side of the 9, it becomes an 8, making the equation 8-7=1 correct.

Did you manage to figure it out? If so, congratulations! If not, don’t worry—practice makes perfect. Engage with more puzzles to keep your mind sharp and improve your problem-solving abilities. Remember, the more you challenge your brain, the stronger it becomes.
