Who can solve this mathematical hole, and what are the three major mathematical holes

This is a psychological suggestion that leads you to think in the wrong way.

I'll give you a look.

A total of 40 yuan, the boss received 35 yuan, 4 people got 4 yuan, and the waiter took 1 yuan, just right.

Think about it in another way, 4 people, 9 yuan each, a total of 36 yuan, which already includes the boss's 35 yuan and the waiter's 1 yuan. So 36 should be 4 yuan for 4 people.

Spending and getting are confused.

Before the offer. Consumer: 4 people, each out of 10 yuan = get the boss 40 discount. Consumer: 4 people, each person out 9 yuan = get the party, the boss 35 + the waiter 1 yuan.

Therefore, after returning, it should be accommodation fee 35 + tip 1 yuan = payer 36 There is no concept of 40.

The 4 yuan was in the pockets of those 4 people.

This isn't a vulnerability, is it a problem?

35 yuan for the hotel, one for the waiter, exactly 36, what is there to ask?

Each person took out 10 pieces and took back one, exactly 36, what is there to ask?

That's not how it works, and the following sentence is the problem:

The three of them each paid 10 yuan to make up 40 yuan and handed it over to the boss, so the analysis described below is also a fallacy

Are you right?

I don't understand how the landlord would ask such a question.

In fact, this algorithm is not right, the correct algorithm: 97 yuan for the boss, 1 yuan for each parent, and 1 yuan for Xiao Ming.

Or it can also be calculated like this: borrow 50 yuan from each parent, and return 1 yuan each, that is, a total of 98 yuan, 97 yuan to the boss, and 1 yuan to Xiao Ming.

The main problem of this problem is Xiao Ming's 1 yuan, and in the end, the sum of his parents and Xiao Ming should not be calculated, but the 98 yuan that his parents actually lent to Xiao Ming minus Xiao Ming's 1 yuan, and the result is 97 yuan for the store owner.

This is a stealing concept, deliberately confusing people, in fact, after Xiao Ming paid back the denominator money, the amount of money he borrowed was only 98 yuan.

This is a brain teaser, bullshit hole.

I only borrowed 98 yuan from my parents, gave 97 yuan to the boss, and left 1 yuan for myself.

There are three major vulnerabilities in mathematics, involving mathematical concepts such as irrational numbers, calculus, and sets.

1. Hipas (hippasus, a native of Mithabangden, around 470 B.C.) discovered the hypotenuse of an isosceles right triangle with a waist of 1 (i.e., Liang Xunsun of the 2nd power root) that can never be represented by the simplest Changsan ratio (not a common ratio).

Thus the first irrational number was discovered, overthrowing the famous theory of Pythagoras. Legend has it that the Pythagoreans were at sea at the time, but because of this discovery, they threw Hibas into the sea.

2. The rationality of the calculus rubber chain has been seriously questioned, and the entire calculus theory is almost overthrown.

3. Russell's paradox: S is composed of a collection of all elements that are not themselves, so does S belong to S? In layman's terms, Xiao Ming said one day:

I'm lying! "Ask Xiao Ming if he is lying or telling the truth. The terrible thing about Russell's paradox is that it doesn't involve advanced knowledge of sets like the greatest ordinal paradox or the greatest cardinality paradox, it's simple, but it can easily destroy set theory.

Controversy in the world of mathematics: Zeno's paradox.

This is also a controversy in the physics community, Achilles races against Zeno the tortoise, and the tortoise runs 100 meters in front of Arischi before Achilles starts running.

When Achilles ran 100 meters, the turtle ran one more meter, and when Achilles ran one meter, the turtle ran another centimeter, and it follows that Achilles would never be able to outrun the turtle. Although in reality, it will run away quickly, but in mathematics, it seems that it will never be able to catch up.

This question is a number game, because ten yuan is included in the money owed, which should be 980 = 970 + 10. Or 1000 = 970 + 20 + 10. This question is exactly ten dollars, which is easy to confuse, but it can be changed:

It cost ten yuan to buy shoes, and ten yuan to pay back to my parents, and I also owe 490 per person, but there is 970 left, if 970 + 980 = wow, 1950!! Earn a lot of money... The result is meaningless...

After returning to my parents, I have 980 left, 970 to buy shoes, and 10 yuan left....I've changed the concept...In fact, my ten dollars have been included in the 980 I owe my parents...It shouldn't be taken out on its own....Plus 10 yuan per person....Whole 1000

You bought 970 yuan, so you owe 970 yuan, plus the 30 yuan that you made up for is enough for 1,000 yuan, no problem.

This is a problem for the calculator, not a bug in the math. It's like buying an apple and buying an apple, how many apples are there? But you count it like this: 1 1 = 1 (pcs).

Then it's not right, 3 x 9 = 27 yuan + 2 yuan from the waiter = 29 yuan.

This equation itself is wrong, since the three people each pay 9 yuan, then a total of 27 yuan is paid, and the two yuan taken by the waiter is included in the 27 yuan, so the equation should be: 25 (the boss takes) + 2 (the waiter takes) + 3 (returned) = 30, so that one dollar is still there.

They only got 27, the boss got 25, and the guy got 2.

It's 27 + 3 27, which contains 2 pieces that the waiter took and 3 pieces that should be + returned to others.

Those two quick money are included in the 27, and the five dollars that should be subtracted in addition to the savings are exactly 30

1 3 = loop, 1 3x3 = 1, loop x3 = loop, because about.

This is mathematically called the limit.

On the number line, each number has only one corresponding position, and when you take the number closest to 1 in the decile, this number is.

At the percentile at the thousandth percentile.

And every time you expand the size of the number, you will advance a small place in the positive direction on the number line, and eventually you will get the loop = 1 after countless advances.

It's just a theory, and in fact the loop is exactly what it is.

If you study mathematics in college, you will learn it, so try hard.
