### Adding Decimals - YourTeacher.com - Pre Algebra Help

For a complete lesson on adding decimals, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, 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.
