How to write vertical calculation?

The vertical calculation is written as follows:

I. Vertical format

There are two main points in vertical pen calculation: the same sign is aligned, starting with a single number. The format in the exercise book strictly follows the following requirements: the horizontal line formula is written from the left end of the horizontal line grid in the math book.

Vertical: The first addend is written horizontally below the second addend. The plus sign is horizontally aligned with the plus sign. The same number of addends, addends and sums must be aligned. After the vertical calculation, don't miss the horizontal figures.

Second, the vertical calculation method

Addition. The same numbers are aligned. If the sum exceeds 10, proceed to 1. (The numbers should be aligned. )

Subtraction. If the same number is aligned, if it is not reduced enough, borrow 1 from the previous number as 10.

Third, multiplication.

I-bit of one number multiplied by j-bit of another number is added to I-j- 1 bit of the product. 10 directly against it. Organization. When calculating the vertical frequency division, start with most significant bit. If it can't be divided, then combine the highest bit and the next bit into a number to divide it until it is divided.

The role of vertical calculation

1, accurate calculation

Vertical calculation can accurately obtain the calculation results and avoid the errors caused by approximate calculation or estimation. This is very important for financial, scientific research, engineering and other application scenarios that require accurate calculation.

2, simplify the calculation

Vertical calculation makes the calculation relatively simple and easy to understand by decomposing the complex calculation process into simple steps. This helps to improve the calculation efficiency, especially when dealing with a large number of data or complex calculations.

3. Cultivate mathematical thinking

As an important part of mathematics education, vertical calculation is helpful to cultivate students' mathematical thinking and logical reasoning ability. By studying vertical calculation, students can better understand mathematical concepts, master the operation rules and improve their ability to solve practical problems. To sum up, vertical computing plays an important role in daily life and academic fields.
