1, addition and subtraction: this is the most basic algorithm used to calculate the sum or difference of two numbers. For example, 5+3 = 8, 10-2 = 8. Multiplication and Division: These two algorithms are used to calculate the product or quotient of two numbers. For example, 5*3= 15, 10/2=5. Power operation: This algorithm is used to calculate a certain power of a number. For example, the third power of 2 is equal to 8, which means 2 3 = 8.
2. Square root and cube root: These two algorithms are used to calculate the square root or cube root of a number. For example, √9=3, that is, the square root of 9 is equal to 3; So is the cube root. Logarithmic operation: This algorithm is used to calculate the logarithm of a number. For example, log2(8) equals 3, that is, the cubic of 2 equals 8.
3. Trigonometric function operation: This algorithm is used to calculate the value of trigonometric function. For example, sin(π/4)=0.707, that is, the sine value of π/4 is equal to 0.707. Exponential and logarithmic function operations: These two algorithms are used to calculate the values of exponential and logarithmic functions. For example, e (2) equals 7.389, that is, the quadratic power of e equals 7.389; Log( 10) is equal to 1, that is, the logarithm of 10 is equal to 1.
The benefits of learning mathematical operations
1. Mathematical operation ability is an important basis for learning mathematics and other disciplines. Because of the large proportion of calculation teaching in primary school mathematics textbooks, students' calculation ability directly affects their learning quality. In addition, the definition of mathematical knowledge, mathematical thinking and thinking concept is also the basis for us to exercise children's mathematical thinking ability from an early age.
2. Mathematical operation is the foundation of all sciences. All major scientific and technological progress is closely related to mathematics. Without mathematics, there would be no computers, televisions and space shuttles, and there would be no such colorful life today. Mathematics is a tool discipline, the basis of learning other disciplines, and also a discipline to improve people's judgment, analysis and understanding.
3. By learning mathematical operations, we can better understand and solve various practical problems. For example, in the engineering field, trigonometric functions are used to calculate angles; In the financial field, the compound interest formula is used to calculate the return on investment and so on. Therefore, mastering computing skills is of great significance to our life and work.
