Access full lesson containing this video at: http://www.yourteacher.com/prealgebra/addingdecimals.php Students learn to add decimals by first lining up the decimal points, then adding the numbers by column. For example, to add 14.2 + 2.86, first line up the decimal points, then add the digits in the hundredths column, to get 0 + 6, or 6, then add the digits in the tenths column, to get 2 + 8, or 10, so write a 0 in the tenths column and carry the 1 to the units column, then add the digits in units column, to get 1 + 4 + 2, or 7, then add the digits in the tens column, to get 1. So 14.2 + 2.86 = 17.06.
