Shang Jiu formula has a total of 9 sentences:

See one without division for ninety-one, see two without division for ninety-two, see three without division for ninety-three, see four without division for ninety-four, see five without division for ninety-five, see six without division for ninety-six, see seven without division for ninety-seven, see eight without division for ninety-eight, see nine without division for ninety-nine.

The divisor is a division of a single number, which is called "single return"; The division of the divisor by two or more digits is called "division", the first step of the divisor is called "division", and the following is called "division". For example, the divisor is the division of 534, which is called "five to three or four divisions". That is, after using the five-return formula to seek business, then divide by 34.

Today I will teach you how to play abacus, super simple and practical, come and learn it.

One up, two on two, three on three, four on four, five on five, six on six, seven on seven, eight on eight, nine on nine.

Common terms. Neutral: When the upper and lower parts of a certain gear are away from the beam, it is called neutral. A blank bin indicates that there is no count in this file, or it means 0.

Empty disk: Each file of the abacus is empty, which means that there is no counting in the whole disk, which is called an empty disk.

Inner beads: The abacus beads that count by the beam are called inner beads.

Outer beads: The abacus beads that are not counted from the beam are called outer beads.

Dial up: refers to the lower bead dial against the beam.

Dial down: refers to the upper bead dialed against the beam.

Dial off: refers to the upper or lower bead off the beam.

Intention plate is a mantra is required:

7. Abacus open square, generally there are half ninety-nine open flat method, product difference open flat method, formula open flat method, multiplication open square, open cubic method, there is a triple root open method, too large business open method. There are many kinds of open fifth, and the common one is to increase and multiply to the fifth power. The opening of the high power is generally rarely used in abacus.

Going to plate addition formula:

1. First of all, you must memorize the formulas of addition, subtraction, multiplication, and division.

2. Secondly, practice fingering more on the abacus, practicing fingering is the key to playing a good abacus, and if you practice fingering, you can not only play fast in operation, but also play accurately without beads.

3. Then, find some questions to combine with mantras to practice how big and how much you play, and you will be proficient.

4. Finally, if you want to play or participate in a game quickly, you can learn the shortcut method of planning the board. For example, mental arithmetic and oral arithmetic are combined into three lines to play, and you can also play with both hands, and multiplication can be multiplied before the empty disk, etc.

5. In short, if you want to make the abacus well, fast and accurate, the only way is to practice more.
