1, interesting math story
Thales saw that people were reading the notice, so he went to check it. The initial notice said that Pharaoh wanted the smartest person in the world to measure the height of the pyramid. So I went to Pharaoh.
Pharaoh asked Thales what tools he used to measure the pyramids. Thales said he only used a stick and a ruler. He put the stick next to the pyramid. When the shadow of the stick was as long as the stick, he measured the length of the shadow of the pyramid and half the length of the bottom of the pyramid. Add these two lengths to get the height of the pyramid. Thales is really the smartest man in the world. He can easily measure the height of the pyramid without climbing to the top.
2. Interesting math story
During the Warring States Period, Qi Weiwang and Tian Ji raced, and Qi Weiwang and Tian Ji each had three good horses: getting on, winning and dismounting. The race is divided into three times, and thousands of dollars are bet on each horse race. Because the horsepower of the two horses is almost the same, and Qi Weiwang's horse is better than Tian Ji's, most people think that Tian Ji will lose.
However, Tian Ji took the advice of his disciple Sun Bin (a famous strategist) and dismounted Qi Weiwang's horse, Ma Zhong of Qi Weiwang and Qi Weiwang. As a result, Tian Ji beat Qi Weiwang 2-/kloc-0-and won a lot of money. This is an example of China's ancient substitution game theory to solve problems.

Mathematical problem
First, is it earned or lost?
Boss Yu bought two ancient coins and later sold them at the price of each 60 yuan. One of them made 20% and the other lost 20%. I want to ask: compared with the two ancient coins he bought at the beginning, is boss Yu a winner or a loser, or just the same?
Second, calculate the breeding number of rabbits.
Rabbits are very productive. A pair of rabbits can give birth to a pair of rabbits every month, and a pair of rabbits begin to give birth to rabbits in the month after birth. How many pairs of rabbits can you breed a year from a pair of newborn rabbits?
I recommend it carefully.
