Unfortunately, children are now almost do not know how to perform calculations in mind.This was due to the fact that modern technology offers every child to solve a problem a couple of clicks.Many children Internet has replaced not only books, but also certain skills.Increasingly, you can hear from the young generation, to know that math is not necessary, because there is always at hand calculator or phone.But the true value of this science is the development of thinking, and not overcome the fear of being deceived by a trader in the market.
long division helps students lower grades to meet the operations on numbers.Thanks to him, fixed in memory the multiplication table, and perform actions to hone skills of addition and subtraction.
To this arithmetic operation is necessary to get acquainted with its components:
1. Dividend - a number that is subject to division.
2. Divider - the number by which divide.
3. Private - the result obtained by dividing.
4. Balance - of the dividend, which is not amenable to division.
American and European models of long division
long division rules are the same in all countries.There is only a difference in the graphical part, that is in his record.In the European system of dividing line, or the so-called Area, is placed to the right of the number of dividend.The divider is written above the line area, and private - a horizontal line corner.
long division of the American model involves setting a corner from the left.Private written above the horizontal line of the corner, just above the divisible number.Divider recorded under the horizontal line to the left of the vertical.The process of the action is different from the European model.
long division in the two-digit number
To split a multi-valued on a two-digit number, you must write it according to the diagram, then perform an action.Long division begins with the higher number of bits of the dividend.Taken the first two digits if the number formed by the value of the divisor.Otherwise, the first three digits are separated.They formed the number is divided by the divisor, the remainder goes down, and the result is written in the separation area.After this number is transferred from the following discharge of the dividend, and the procedure is repeated.This continues until the number will not be divided completely.
If you want to share with the remainder of the number, it is written separately.If you want to completely separate the number, the number of digits after the comma in the response indicating the start of a fractional part, and instead bit numbers each time demolished down to zero.
long division develops attentiveness and perseverance, logical thinking and memory.It is important to remember how to perform this action, if necessary, to share the precious knowledge with their children and help them with homework.
