Adding Multi-Digit Numbers

Addition is the process of finding the total or sum by combining two or more numbers.

A multi-digit number is a number that has two or more digits, such as 23, 456, or 1,234.

To add multi-digit numbers, align the numbers by their place values (ones, tens, hundreds, etc.) and add each column starting from the right.

Carrying is a process used in addition when the sum of a column exceeds 9, moving the extra value to the next column on the left.
