The process of long addition is a technique used to add two or more numerical figures. This method requires that numbers be aligned according to their place values, such as units, tens, hundreds, etc. The addition begins from the rightmost column (units) and moves towards the left. If the sum of a column is greater than 9, the "carry" is transferred and added to the subsequent left column.
