How to multiply in a column

The multiplication in column one of the first and the most important operations, which studies the young learner in school. Without a clear knowledge and understanding of the whole sequence of actions when multiplying two numbers it is impossible to acquire further knowledge of mathematics. To fully learn how to multiply in a column can only be a multiple repetition of this operation. Performing the computation in a column, the student trains memory and attention. This allows further easier to concentrate on any task. To multiply numbers in a column need after studying the multiplication tables.

You will need

• A piece of paper in the box, handle

Instruction

1. Write down on a piece of two numbers to multiply. The second number is place under the first so that the last digits of the numbers were exactly under each other. Swipe underneath the line. All calculations only write below the line.
2. Take the rightmost digit of the second number and multiply it on the right-most digit of the first number. If you get a two-digit number exactly under multiply numbers write its last digit. Next to a column on a piece of paper, mark the remainder of the first number, or remember it in mind.
3. Again multiply the rightmost digit of the second number is the next digit of the first number to the left. The result of the multiplication, add the previously stored digit from the previous works. If we multiply the digit of the first number was the last record the result completely. If the first number still has digits left, also split the result and make a note under the multiply digits the last digit, and the first remember.
4. Similarly, multiply the remaining numbers of the first number by the rightmost digit of the second. Next, take the next digit of the second number to the left. And, as an extreme figure, multiply it on the line for all the digits of the first number. The results start to burn just under the figure multiplied by the second number and at a lower level than in the previous step.
5. Multiply all the digits of the second number, as described on figures first. In the end, the number of rows of digital recordings should be equal to the number of digits of the second number.
6. Fold the received digital ranks. To do this, add zeros in the empty places in the ranks, in order to make the addition. Draw the line under all the rows. Start adding from the rightmost digit ranks. Fold of numbers are exactly above each other. Upon receipt in the amount of two-digit numbers as well write it down the last digit and keep the highest figure to add to the subsequent amount.
7. After addition of the last, right-most digits of the result record full. And the MSB of the amounts, if any, should be placed to the left of all digits of a number. The number below the last line and is the product of the set of numbers obtained by multiplying in columns.
