Recently, a seemingly impossible match equation has swiped the screen in the circle of friends! The title gives the obviously wrong equation of "9-3=1" and requires that only one match be moved to make it true. This question has made countless academic enthusiasts scratch their ears and cheeks, and even many professors are stunned! But when the answer was revealed, everyone exclaimed, "That's ingenious!"
The solution that most people try:
Turning 9 into 5 or 3, minus into plus, 1 into 7 doesn't make the equation hold
Breakthrough Solution:
Turn the equation backwards!
Move the match at the bottom of "9" to the equal sign, and the original formula becomes "6-5=1", but you need to invert the whole equation to see it
Problem Solving Skills:
Don't limit yourself to the numbers, try to change the overall structure of the equation, think about the many possibilities of match placement, and look at things from a different perspective if necessary
This question teaches us:
1. Solving problems requires an innovative perspective
2. Sometimes the answer is "between thoughts"
3. Fixed thinking is the biggest obstacle
4. Simple problems can have amazing solutions
