Subtracting two columns for a single line result’s a standard process in information evaluation and spreadsheet functions. It includes discovering the distinction between corresponding values in two columns and displaying the lead to a single row.
This operation is beneficial for evaluating information, figuring out developments, and performing calculations. As an illustration, in a spreadsheet containing gross sales information, you might subtract the “Gross sales” column from the “Goal” column to seek out the gross sales variance for every product.
