In mathematics, operation refers to the process of operating some numbers or algebraic expressions according to certain rules or sequences to obtain new results. According to the complexity and level of operation, it can be divided into primary operation and secondary operation.
One-level operation, also known as unary operation or simple operation, is a simple operation only on one or more variables, such as addition, subtraction, multiplication and division. These operations are based on basic mathematical concepts, which are relatively simple and easy to master.
Specifically, addition is the process of combining two or more numbers into one number, subtraction is the inverse process of addition, that is, one number or quantity subtracts another number or quantity, multiplication is the process of multiplying two numbers, and division is the inverse process of multiplication, that is, the process of dividing one number by another to get quotient.
Quadratic operation, also known as binary operation or complex operation, involves complex operations of two or more variables, such as square, square root, power and root. These operations are more complicated than the first-level operations, and require more advanced mathematical knowledge and skills to understand and apply.
Specifically, a square is a process of multiplying a number by itself twice, a square root is a process of dividing a number by itself once, a power is a process of multiplying a number by all possible combinations of another number to get a new number, and a root is a process of square root of a number.
The first-level operation is unary operation or simple operation, including basic mathematical concepts such as addition, subtraction, multiplication and division. Quadratic operation, also known as binary operation or complex operation, involves complex operations of two or more variables, such as square, square root, power and root.
It should be noted that there are more and more complex operations in mathematics. However, primary operation and secondary operation provide a basic classification method, which can help people better understand different levels of operations and their applications.
In addition, in computer programming, these basic mathematical operations will also be used as the basis for constructing more complex algorithms. Therefore, it is very important to learn and understand these basic mathematical operations.
