How to arrange vertically?

Column vertical is a mathematical calculation method, which is suitable for addition, subtraction, multiplication and division of multiple digits. The following are the basic steps for vertical columns:

Determine the number of digits to be calculated, and arrange them in the order of unit, ten, hundred, etc.

According to the operation to be performed, align the numbers on each bit and leave the position of the result on the bottom line.

Start from the unit, calculate in turn, and fill in the results in the following position. Pay attention to the handling of carry and borrow.

Finally, add or subtract all the results to write the final result.

To give a simple example, suppose 1234 x 567 is calculated, and the steps of column verticality are as follows:

It should be noted that the staggered calculation method is suitable for most mathematical problems, but it may need to be adjusted and changed according to specific problems in actual operation.
