How is the division into a column

Unfortunately, children are now practicallydo not know how to make calculations in the mind. This was due to the fact that modern technology offers each child to solve the problem with a couple of clicks. For many children, the Internet has replaced not only textbooks, but certain skills. Increasingly, you can hear from the younger generation that you do not need to know mathematics, because you always have a calculator or phone at hand. But the true value of this science lies in the development of thinking, and not in overcoming the fear of being deceived by a trader in the market.

The division into a column helps students of juniorclasses to get acquainted with operations on numbers. Thanks to it, the multiplication table is fixed in memory, and the skill of performing the addition and subtraction operations is honed.

To implement this arithmetic action, it is necessary to get acquainted with its components:

1. The Divisible is the number that undergoes division.

2. Divisor is the number by which to divide.

3. The quotient is the result obtained by division.

4. The remainder is part of the dividend that can not be divided.

American and European models of division into a column

The rules of division into a column are the same in allcountries. There is only a difference in the graphic part, that is, in its record. In the European system, the dividing line, or the so-called corner, is placed on the right side of the dividend number. The divisor is recorded above the line of the corner, and the divisor is recorded under the horizontal slope of the corner.

Division into a column according to the American modelprovides for setting the corner on the left side. Private is recorded over the horizontal line of the corner, just above the divisible number. The divisor is written under the horizontal bar, to the left of the vertical bar. The process of performing the action itself does not differ from the European model.

Division by a column into a two-digit number

To divide a multivalued number into a two-digit number,it is necessary to record it according to the scheme, after which to carry out the action. Division into a column begins with the highest digits of a divisible number. The first two digits are taken if the number formed by them is greater than the divisor by value. Otherwise, the first three digits are separated. The number formed by them is divided into a divisor, the remainder goes down, and the result is recorded in the dividing corner. After that, the digit from the next digit of the dividend number is transferred, and the procedure is repeated. This continues until the number is completely divided.

If you want to divide a number with a remainder, then itis recorded separately. If it is required to completely separate the number, then after the end of the digits of the number in the response, a comma is placed indicating the beginning of the fractional part, and instead of the digit numbers, each time zero is taken down.

The division into the column develops attentiveness andperseverance, logical thinking and memory. It is important to remember how this action is carried out, if necessary, to share precious knowledge with your children and help them with their homework.
