Dear, can you be clearer a little more?

Hehe, the waiter's 2 pieces are now included in 27 pieces! The three of them gave a total of 30 yuan, gave 25 yuan to the boss, and the waiter stole 2 yuan, and they still had 3 yuan left!
3 times 9 = 27 This is all the money that three people actually go out of The formula is =30-25-2=3

Wine 7 glasses 2, grapes 1 grain, so 7 2 + 2 2 5 = 34.

One apple is equal to 7
One grape is equal to 5+7
One apple is equal to 1 + 3 bananas (note **, it is 3) [so one banana is equal to 2] one apple + grape + one banana, equals.

This dollar is at the boss's; The algorithm you said looks reasonable, but it's actually wrong, and it should be counted like this:
3 9 = 27 There is nothing wrong with the consumption of three people.
25 + 2 = 27 The sum of the money the boss and the guy is right27 = 27 No more, no less

This kind of question has been asked badly. The answer is that the algorithm is different. Both algorithms are correct on their own, but they can't be compared.
Let's say you have 100 quick money, you use 40 for the first time, you use 60 and then you use 10 dollars and you use 50 and then you use 50 to run out.
The algorithm that mimics him is.
You have a total of 40 plus 10 plus 50, for a total of 100 pieces.
You have a total of 60 plus 50 plus 0,110 left
Can you explain how the 10 dollars came from?

There are so many people asking this question lately, please refer to the following. Spending exactly 50 and the rest adding up are two different things. It's not equal in the first place, and that's just deception.
If you look at the one on the right side of the picture below, you can spend it like this, and the rest of it adds up to 144 yuan.

9 yuan per person, a total of 27, including the 2 yuan hidden by the waiter, can't be added, it doesn't make sense.

Briefly talk about the flow process of this 30 yuan.
At first, it was 10 yuan per person.
Later, after paying the money the boss 30 yuan.
After the money is refunded the boss 25 dude 5
In the end, after returning the money, the boss 25 guys, 2 guests, 1 each, so look at it, the money is right.
So according to the algorithm in the question, what went wrong?
The fault is that the total amount of money has changed, and it is no longer 30 yuan. It's $27.
Because after returning 1 yuan per person, it is equivalent to 9 yuan per person. That is to say, a total of 27 yuan was paid.
The boss gets $25 and the guy $2.

Short for where are you, a term used in web chat.
btw (by the way): This is what most people use, which means "by the way". >>>More
Neither end is planted with a tree, or neither end is counted, so according to this kind of problem, it is difficult to calculate that he must subtract one end of the result, so he must subtract one.
Running is a great exercise, but pay attention to the method. >>>More
No way! Euler studied and solved this problem in 1736, and he reduced the problem to the "one-stroke" problem shown in the picture on the right, proving that the above move was impossible.
