In a vertical division, there are usually two numbers (dividend and divisor) and an operator (÷), as well as some symbols used for calculation (such as |,-,0, etc.). ).
Write the dividend and divisor above the vertical line first, and the operator in the middle. In this column, we will write 45÷3. Next, put the divisor 3 below the vertical center line and the dividend 45 to its left.
Next, starting with the number of digits of the dividend, each digit should be operated with each digit of the dividend. In the vertical form, from right to left, it corresponds to the unit, tenth and hundredth of the dividend, and the unit, tenth and hundredth of the divisor respectively. For example, first calculate the divisor unit (5) and then divide it by the divisor unit (3) to get the quotient 1+2, and write 1 above the vertical center line.
Write the remainder 2 below the vertical center line. Then calculate the ten digits (4) divided by the ten digits (3) to get the quotient 1 and the remainder 1. Write the quotient 1 above the vertical centerline and the remainder 1 below the vertical centerline. Finally, calculate the number of hundreds (4) and divide by the number of hundreds (3) to get the quotient 1 and the remainder 1. Write 1 above the vertical centerline and the rest 1 below the vertical centerline.
Advantages of learning mathematics
People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Mathematics is the foundation of other disciplines, and it is easier for people who learn mathematics well to get into other disciplines. Learning software, computer, finance and other engineering majors is even more handy.
It is used everywhere in life. Nowadays, the society is an information society, and mathematical knowledge is used in financial management and computers. Mathematics can cultivate people's integrity and honesty. Mathematics pays the most attention to convincing people by reasoning, and only believes in the results of logical reasoning. Mathematics can cultivate people's tenacity and courage. Mathematics can cultivate people's overall consciousness. Mathematics can cultivate people's good character.
