The divisor of division is calculated according to quotient, remainder and dividend, which can be calculated according to the formula: dividend = divisor × quotient+remainder.

1. Calculate the divisor according to the remainder.

1, division is a basic mathematical operation, involving the concepts of divisor, dividend, quotient, remainder and so on. Among them, divisor is a key parameter, which determines the result of division.

2. In the division operation, dividend is the sum of the quotient and the remainder obtained by dividing dividend by divisor. Therefore, if the quotient and remainder are known, the divisor can be calculated by the formula "Dividend = Divider× Quotient+Remainder".

Second, the daily use of the formula

1, addition formula: addition is one of the basic operations of mathematics. When we have two or more numbers added together, we can use the addition formula to calculate their sum.

2. Subtraction formula: Subtraction is the operation of subtracting one number from another. When we have two numbers to subtract, we can use the subtraction formula to calculate their difference. For example, to calculate 8-4-2, we can use the subtraction formula 8-4-2=8-6=2.

3. Multiplication formula: Multiplication is the operation of multiplying two numbers. When we multiply two numbers, we can use the multiplication formula to calculate their products.

4. Division formula: Division is the operation of dividing one number by another. When we divide two numbers, we can use the division formula to calculate their quotient.

Divisibility: the basis of mathematical logic and the tool of practical application

1, the basis of mathematical logic

Divisibility is one of the foundations of mathematical logic, which helps us to understand how to decompose a number into several factors reasonably and accurately, so as to better grasp the essence of this number.

Step 2: Practical tools

The concept of divisibility is widely used in real life. For example, in computer science, divisibility can be used to determine important issues such as the size of data storage space and data organization; In business, divisibility can help people distribute goods and calculate inventory.

3. The cultivation of mathematical literacy

The concept of divisibility is one of the important ways to cultivate people's mathematical literacy. Learning and practicing the concept of divisibility can improve people's mathematical thinking, logical thinking and problem-solving ability. Divisibility is an accurate and orderly way of thinking, which is of great significance to cultivate people's mathematical literacy and comprehensive quality.
