A, division of vertical calculation steps:

1, what are the steps:

Vertical one * * * is divided into two steps, namely vertical column division and vertical lifting method. The formula is to list the dividend and divisor vertically, and the solution is to input the answer and work it out.

2. Vertical division formula:

First, erect the dividend and divisor according to the number of digits, with the dividend at the top and the divisor at the bottom, and separate them with horizontal lines.

3, vertical segmentation solution:

Divide two numbers by an operation symbol. When calculating, start from the first number on the left, divide the dividend by the current divisor in turn, and then write the result below the vertical line. If it is not divisible, mark the remainder.

Second, the vertical column matters needing attention:

1, alignment:

Pay attention to alignment when calculating, and calculate bit by bit to avoid calculation errors.

2, the location of the product:

The product of quotient and divisor is written below the dividend.

3. Location of land difference:

Write the difference between the dividend and the product of quotient and divisor under the horizontal line.

4. Keep the decimal point:

In the calculation results, decimal points need to be kept.

5. Understand mathematical concepts:

In the process of calculation, we need to pay attention to understand the mathematical concepts such as110000, 1% to avoid errors in the calculation results.

Definition, characteristics, advantages and disadvantages of vertical type;

First, the definition of vertical:

1, definition and interpretation:

A vertical type is an expression represented by a vertical column. Usually used in advanced mathematics or complex calculation problems. In vertical form, all numbers are arranged in vertical columns, and then bitwise addition, subtraction, multiplication or division are performed.

2. Example:

For example, 4× 12= 48 is the vertical type.

Second, the vertical characteristics:

The characteristic of vertical type is that each column is a number, which is very convenient to use in the calculation of complex multi-digit numbers that are difficult to write in horizontal type.

Third, the advantages and disadvantages of vertical:

1, advantages:

It is suitable for multi-digit calculation and can ensure the calculation accuracy.

2. Disadvantages:

The calculation process is complicated and not suitable for oral calculation. In addition, sometimes it is necessary to calculate vertical borrowing and carry, which is easy to make mistakes.
