Ma Yun has 500 billion, and China is a country with a population of1300 million. If everyone is given100 billion, he still has 498.7 billion. Aren't we all billionaires?

Ma Yun has 500 billion, and China is a country with a population of1300 million. If everyone is given100 billion, he still has 498.7 billion. This is not right.

Ma Yun has a population of 500 billion, and China has a population of 1 300 million. The unit of counting these two figures is1100 million.

If China 1300 million people per person1300 million, the total should be1300 million yuan, that is 13 * 10 16.

And Ma Yun's 500 billion is written as 5 * 10 8.

13* 10^ 16>； 5* 10^8

Ma Yun's money is not enough for 1 300 million people per person1100 million.

If there is 498.7 billion yuan left according to the meaning of the question, it should be 1 yuan per person.

In other words, if we take out1*13 =1300 million yuan, then 500 billion yuan will leave 498.7 billion yuan.

Mathematical language is also difficult for beginners. How to make these words have more accurate meanings than everyday words also puzzles beginners. For example, words such as openness and domain have special meanings in mathematics, and mathematical terms also include proper nouns such as embryo and integrability.

But these special symbols and terms are used for a reason: mathematics needs accuracy more than everyday language. Mathematicians call this requirement for linguistic and logical accuracy "rigor".
