You need to move one matchstick to change the equation. Which matchstick? Move the lower left matchstick of the number 6 in the middle of the equation, and move it to the upper right part of the number 6 in the middle of the equation. We are moving the same matchstick from the same digit and placing it back in the same digit in a different place. With this change, the number 6 in the middle of the equation becomes a 9. That gives us the correct equation: 15-9=6.
