Asking for some fun math problems?? Thank you!!

Zeno tortoise. Achilles was a hero of ancient Greek mythology. In his race with the tortoise, he was ten times faster than the tortoise, the tortoise ran 100 meters in front and he chased behind, but he couldn't catch up with the tortoise.

Because in the race, the pursuer must first reach the starting point of the pursued, and when Achilles chased 100 meters, the turtle had already climbed forward another 10 meters, so a new starting point was born; Achilles had to keep chasing, and when he got to the 10 meters the turtle had climbed, the turtle had already climbed forward another 1 meter, and Achilles could only chase the other 1 meter. In this way, the tortoise will create an infinite number of starting points, and it will always create a distance between the starting point and itself, no matter how small this distance is, but as long as the tortoise keeps trying to climb forward, Achilles will never be able to catch up with the tortoise!

Socrates famously said, "I know only one thing, and that is nothing." ”

In Zeno's view, since the arrow has an instantaneous position at each moment of its flight, it is no different from not moving in this position. So, is the sum of infinite resting positions equal motion? Or is the infinitely repetitive stillness a motion?

It's all a paradox.

9 minus 6 divide 3 is such a simple but error-prone and fun math problem. The more the merrier, thank you!! Sit back and wait for ......

This brother, mathematics must also keep pace with the times!

The other day I read in my sister's elementary school math textbook: "Divide by the abbreviation... That is to say, now dividing and dividing already have the same meaning, both of which mean "divide". No more tongue-twisters like we did when we were in elementary school.

The white hen lays 3 eggs for 1 day, and the black hen lays 1 egg for 3 days. How many days does it take for two chickens to lay a total of 100 eggs?

Tools Materials: Take the Paint tool as an example.

1. First of all, in the interface of the drawing tool, prepare 1 1 1 = 6.

2. Then in the Paint tool interface, associate the three 1s with a plus sign.

3. After that, in the drawing tool interface, add parentheses next to the leftmost and rightmost 1s.

4. Then in the interface of the drawing tool, add an exclamation mark in the small brackets next to the rightmost 1 to show the factorial of the table to get the equation (this 1+1+1)! =3！3*2*1=6, the equation holds.

If you like fun math problems, you may want to try the Einstein IQ test questions as shown in question 17 below.

1] Suppose there is one.

It can be seen that my sister was not born eight years ago.

That is, the younger sister is exactly 6 years old this year, and the elder sister is 6 + 5 = 11 years old.

90 - (3 + 5) 2 = 41

It can be known that his sister Fangchun and her mother are 41 years old this year.

Then: Mom is 41-6=35 years old this year.

Dad is 35 + 3 = 38 years old this year.

Once upon a time, a landlord hired a powerful long-term laborer. He had a piece of gold weighing seven taels. The condition he gave to the long-term workers was one tael of gold a day.

Seven days of work. With only two cuts, he made the long-term workers get the gold every day and could not take credit. How should he spend it???

The two knives cut the gold bar into three pieces weighing one tael (1 7), two taels (2 4) and four taels (4 7).

On the first day, one or two gold bars were given;

The next day, give two taels of this piece, and return one tael, so that he will get two taels;

On the third day, one or two more gold bars are given, and two taels plus one tael is three taels;

On the fourth day, he gave the four taels of the heel, and returned the two of the first and two taels, and he had four taels of wages in his hand;

On the fifth day, give one tael, and add one tael to four taels to get five taels;

On the sixth day, the one who gave two taels returned the one tael, and four taels plus two taels equaled six taels;

On the seventh day, I will give another tael, and the total will be seven taels.

If the police are not there, the prisoner will hurt the family of six, if the father is not there, the mother will hurt the son, and if the mother is not there, the father will hurt the daughter.

Q: How can I get 8 people to cross the river smoothly?
