As they get older, they are introduced to addition algorithms. EDM introduces different methods for addition since some are well suited for mental arithmetic or larger numbers. Some are easier to learn, but not as efficient as others. EDM picks one algorithm...","thumbnail_url":"https:\/\/sau51.org\/pes\/wp-content\/uploads\/2010\/02\/clip-image002-thumb.gif"}
