Recently, I brushed up on a moving pencil to change the equation, "5 5 = 4", which looks simple at first glance, but actually hides ingenuity, which is suitable for fun when chatting with friends.

Let's break down the rules first: the numbers are made of pencils, and only one can be moved, and the numbers or symbols are changed to make the equation true.

At first, I was also confused, how can 5 change? Can the plus sign be changed? I tried to change 5 to 3 and plus to minus, but the results were not right, until I changed my thinking - don't keep knocking on the left, look at the 4 on the right 

The answer is very simple: move the pencil in the upper right corner of the second "5" to the left of the "4" to the right of the equal sign, and "4" directly becomes "9", and the equation becomes "5 5="9".

Isn't it like looking for something in life, staring at a place is useless, and it can be solved instantly from a different angle

This question is interesting because it breaks the fixed thinking. It's like encountering a stuck plan at work, looking at the problem from a different perspective, maybe it will work.

30 of us, we have seen a lot of complicated things, encounter this kind of small puzzle, the moment it is solved, like recovering the joy of playing puzzle games when we were children, simple and decompressing, the next party can test friends, see who can break it in seconds~

(Actually, there is another solution: move the vertical of the "" sign to the first "5", so that "5" becomes "6", and the equation becomes "6- 5=1", but "5 5=9" is more intuitive.) Things in life are the same, there is more than one solution, the key is not to be trapped by "what must be", be flexible, and the road will be wider)
