Mathematical information is the important information obtained in the figure or problem, which is the information related to the solution of the mathematical problem from the description of the stem
for example, how much is manual series and story series How much is handmade series more expensive than story series, or how much is story series cheaper than handmade series. The little girl paid 100 yuan. How much should she have left? It's all mathematical information
Of course, mathematics must be inseparable from numbers, so it can also be said that what can be expressed by numbers is mathematical information extended materials:
Mathematics:
is a discipline that studies the concepts of quantity, structure, change, space and information, and belongs to a kind of formal science from a certain point of view. Mathematicians and philosophers have a series of views on the exact scope and definition of mathematics
in ancient China, mathematics was called arithmetic, also called arithmetic, and finally changed to mathematics. Arithmetic in ancient China was one of the Six Arts (called "number" in the six arts)
mathematics originated from the early proction activities of human beings. Since ancient times, the Babylonians have accumulated a certain amount of mathematical knowledge and can apply it to practical problems. From the perspective of mathematics itself, their mathematical knowledge is only obtained from observation and experience
information:
refers to the objects transmitted and processed by audio, message and communication systems, and generally refers to all the contents transmitted by human society. By obtaining and identifying different information of nature and society, people can distinguish different things and understand and transform the world
In all communication and control systems, information is a form of universal connection. In 1948, mathematician Shannon pointed out in his paper entitled "mathematical theory of communication" that "information is used to eliminate random uncertainty". Information is the most basic universal unit to create all things in the universenetwork mathematics
Network Information
Main learning:
multiplication and division in tables, reading and writing of numbers within ten thousand, addition and subtraction of numbers within ten thousand (without carry and abdication), including the understanding of two-step calculation problems of addition, subtraction, multiplication and division and brackets, that is, the simple four mixed operation rules of two-step calculation
A simple two-step calculation problem. There are also statistics and preliminary knowledge, can use a square to represent 5 or 10, simple understanding of graphics, simple understanding of measurement units such as length units of meters and centimeters, weight units of kilograms and grams, the content is relatively simple we should pay attention to the memory of multiplication formula and the application of multiplication formula in simple table multiplication and division, two-step calculation algorithm and simple two-step calculation application problems
