In the era of big data, when it comes to data, it is necessary to talk about numbers. Numbers have penetrated into every aspect of our lives: phone numbers, bank cards, passwords, ID cards ... all of them are full of numbers, and online transactions are constantly being counted. Numbers have quietly entered our lives and deeply influenced us!
The so-called "big data era" means that for a country with a large population like ours, we have begun to collect a large amount of data and information, and use statistical methods to discover the laws from them to help decision makers make correct and reasonable decisions. A book called "Digital Revolution" has made a profound discussion on the highly digital situation in the future. In the future, digitalization and quantification will surely become a universal feature of society, which will profoundly affect people's thinking and life!
"Please press 1 for payment, 2 for inquiry, 3 for maintenance and 4 for manual service", and such service modes are everywhere now. That is to say, numbers are used to replace specific things or things. This way of thinking is called "symbolic thinking". Most old people are not good at thinking like this. In addition to symbolic thinking, we also face the problem of quantifying things. Whether it is social, economic or other issues, we must quantify things first, because mathematics only deals with numbers!
The so-called "big data" is to quantify all kinds of things and turn them into statistical data, and then apply statistical methods to solve them. Quantify specific things, such thinking is called quantitative thinking! It is the embodiment of quantitative thinking that students solve practical problems. If you can't quantify the problem, then you can't solve it mathematically.
The following questions test your quantitative thinking ability.
When an old rich man died, he said to his pregnant wife, "If a boy is born in the future, two thirds of my property will be given to him and one third to you;" If it's a girl, two thirds for you and one third for her. "Later, my wife gave birth to twins. How do you think to divide the property without going against the wishes of the old rich man?
The above is what Bian Xiao shared with you about the symbolic and quantitative thinking that must be understood in the era of big data. For more information, you can pay attention to the global ivy and share more dry goods.
