To solve this problem, we need to master the definitions and algorithms of addition and multiplication. Addition is one of the basic operations in mathematics, which involves merging two or more numbers into a sum. In addition, we need to add one number to another to get their sum. For example, add 3 and 4 to get their total of 7. Addition can be applied to various numbers, including integers, decimals and fractions.
Multiplication is one of the basic operations in mathematics, which includes multiplying one number by another to get their product. In multiplication, we call one number a factor and the other a multiple. For example, multiply 2 by 3 to get their product 6.
According to the priority, multiplication takes precedence over addition. This means that multiplication will precede addition in the expression. According to the law of association, the operation order of addition and multiplication does not affect the result. That is, when multiple addends or factors are added or multiplied, their order will not affect the final answer. In order of priority, the result will be 220168001.1.
The importance of mathematical calculation:
1, mathematical calculation is the key to solve various practical problems. In daily life and work, people often need to solve various quantitative relationships and spatial forms, such as calculating prices, calculating areas and volumes, and evaluating investment risks when shopping. Through mathematical calculation, people can analyze, understand and solve these problems more accurately and make more wise decisions.
2. Mathematical calculation is the basis of scientific research and engineering design. In scientific research, it is necessary to carry out various numerical calculations and data analysis, such as calculating the model of physical phenomena, predicting future trends, optimizing design and experimental results. In engineering design, various mathematical calculations are needed, such as calculating structural strength, optimizing design scheme and reducing cost. Through mathematical calculation, scientists and engineers can describe natural phenomena and design concepts more accurately, and improve the efficiency and accuracy of research and practice.
3. Mathematical calculation is an important way to cultivate students' logical thinking and innovative ability. Through mathematical calculation, students can gradually master the basic concepts, principles and methods of mathematics and cultivate their logical thinking ability and problem-solving ability. At the same time, mathematical calculation can also stimulate students' innovative consciousness and creativity, help them explore new ideas and methods, and expand their horizons and ways of thinking.
