How to calculate the division formula of grade three?
Generally, it is calculated according to the steps of division, such as 64÷2=32 1.
How to read the division formula: division by divisor equals quotient, division by quotient equals divisor, and quotient multiplied by divisor equals dividend.
Names of each part of the division formula: dividend is the total number, divisor is the number of known numbers, and quotient is the number of unknown numbers.
Calculation method of division formula: divide the known number into the unknown number in turn.
How to calculate division?
Division is a basic mathematical operation, and its calculation method is: dividend ÷ divisor = quotient.
For example, if we have two numbers, 9 and 2, we can divide 9 by 2.
Dividend is: 9 Dividend is: 9; Divider: 2 Divider: 2; 9÷2=4.59÷2=4.5; So, the result of dividing 9 by 2 is 4.5.
What is the difference between division and multiplication?
Multiplication and division are two basic operations in mathematics, and they have different operation rules and meanings.
Multiplication is an extension of addition, which can multiply two or more numbers to get their sum. For example, 3 times 4 equals 12, which means 3 plus 3 plus 3 equals 12. Multiplication is very common in daily life, such as calculating the number and area of items.
Division is the inverse operation of multiplication, which can divide a number into several equal parts. For example, 12 divided by 3 equals 4, which means that 12 can be divided into three equal parts of 4. Division is very useful in solving practical problems, such as calculating the average value and assigning items.
In addition, multiplication and division are also widely used in mathematics. For example, in algebra, they can be used to solve equations; In probability theory, they can be used to calculate probability; In geometry, they can be used to calculate area and volume.
In a word, multiplication and division is a very important basic operation in mathematics, which is widely used in solving practical problems and scientific calculation.
