1. Decompose 2-9 into the sum of several non-decomposable positive integers, which is the synthesis of this number.
Therefore, the decomposition and composition of 2-9 are as follows:
1, 2 can be decomposed into the sum of 1 positive integers.
2 and 3 can be decomposed into the sum of two positive integers.
3 and 4 can be decomposed into the sum of three positive integers.
4 and 5 can be decomposed into the sum of five positive integers.
5 and 6 can be decomposed into the sum of six positive integers.
6,7 can be decomposed into the sum of 7 positive integers.
7 and 8 can be decomposed into the sum of 8 positive integers.
8 and 9 can be decomposed into the sum of 9 positive integers.
Second, the decomposition formula in 10 is:
1 is decomposed into 0 and 1.
2 is decomposed into 0 and 2, or 1 and 1.
3 is decomposed into 0 and 3, or 1 and 2.
4 is decomposed into 0 and 4, or 1 and 3, or 2 and 2.
5 is decomposed into 0 and 5, or 1 and 4, or 2 and 3.
6 is decomposed into 0 and 6 or 1 and 5 or 2 and 4 or 3 and 3.
7 is decomposed into 0 and 7 or 1 and 6 or 2 and 5 or 3 and 4.
8 is decomposed into 0 and 8, or 1 and 7, or 2 and 6, or 3 and 5, or 4 and 4.
9 is decomposed into 0 and 9 or 1 and 8 or 2 and 7 or 3 and 6 or 4 and 5.
Importance of decomposition
Decomposition refers to the decomposition of complex things or concepts into simpler and easier-to-understand parts for better understanding and solution. Decomposition helps us to deeply understand the essence and structure of things, so as to better understand and solve problems. Here are some meanings of decomposition and the subheadings of each paragraph:
1, simplify the problem:
Decomposition can simplify complex problems into simpler ones, so that we can understand and solve them more easily. For example, decomposing a big mathematical problem into smaller sub-problems can solve each sub-problem more easily and finally solve the whole problem.
2. Better understand:
Decomposition can decompose a complex concept or thing into simpler parts so that we can understand it better. For example, decomposing a complex chemical reaction into a simpler chemical reaction can help us better understand the nature and process of chemical reaction.
3, gradually solve:
Decomposition can decompose complex processes or tasks into simpler steps, so that we can solve them step by step. For example, breaking down a complex programming task into smaller steps can help us understand each step more easily and solve the problem step by step.
4. Improve efficiency:
Decomposition can decompose a complex task into simpler tasks, so that we can finish them faster. For example, breaking down a complex report writing task into smaller tasks can help us complete each task faster and improve work efficiency.
5, innovation and creation:
Decomposition can help us discover new ideas and create new inventions. For example, breaking down existing products or services into simpler parts can help us discover new innovations and improvements, thus creating new products or services.
