Long addition, also known as column addition or vertical addition, is a method of adding two or more numbers by aligning them vertically and performing addition digit by digit, starting from the rightmost (units) digit and moving towards the left, carrying over any excess values to the next column as needed. It is one of the basic arithmetic operations and is taught in elementary mathematics education.

## All Formulae Related to Long Addition Calculator

Long addition, also known as column addition or vertical addition, doesn’t involve specific formulas like more complex mathematical operations. Instead, it’s a straightforward method for adding numbers. Here’s a step-by-step guide on how to perform long addition:

Step 1: Align the numbers vertically, with their rightmost digits (units place) in the same column.

Step 2: Add the digits in the units place (rightmost column) together. If the sum is 10 or greater, write down the ones digit and carry over the tens digit to the next column to the left.

Step 3: Move to the next column to the left and add the digits in that column, along with any carried-over tens digits from the previous step. Write down the ones digit of the sum and carry over the tens digit if necessary.

Step 4: Repeat Step 3 for each subsequent column to the left until you have added all the digits.

Step 5: If there is a carry-over digit after adding the leftmost column, write it down as part of the result.

Here’s an example of long addition:

`456 + 789 ______`

1. Add the units place: 6 + 9 = 15. Write down 5 and carry over 1.

`456 + 789 ______ 5`

1. Move to the tens place: 1 (carry-over) + 5 + 8 = 14. Write down 4 and carry over 1.

`456 + 789 ______ 45`

1. Move to the hundreds place: 1 (carry-over) + 4 + 7 = 12. Write down 2.

`456 + 789 ______ 1245`

This is the result of the long addition.
