# About This Calculator
Long Addition is the standard algorithm taught in schools for adding multi-digit numbers. It involves lining up numbers vertically by their place value (ones, tens, hundreds, etc.).
When the sum of a column is 10 or greater, the 'tens' portion is carried over to the next column on the left.
